Above $2000, Gas Grills start getting shiny and in a good way. At this price point, we start to see what looks like professional grilling equipment. I would argue that nothing here is that good, but there are definitely some great grills to be found between $2000 and $4000 (based on a combination of suggested retail price and actual retail price). In recent years, a number of the heavyweights in the high-end grilling business have introduced lower-cost versions of their products. Twin Eagles has their Delta Heat line. Lynx has their Sedona line. And Alfresco has its Artisan line. This is also where we find the highest end products from companies like Weber and Broil-King. These truly are the Best Gas Grills between $2000 and $4000.
Delta Heat 32-Inch
Find out more about the Delta Heat 32-Inch Gas Grill
Twin Eagles makes some of the best gas grills on the market. Their Delta Heat line is designed to be a less expensive alternative to the main brand. While a few hundred over three thousand sounds like a lot, this grill has complete 304 stainless steel construction, three 20,000 BTU main burners and it is made in the United States. There are several similarly priced products that have none of this. Delta Heat has a complete line of outdoor kitchen products and this model is generally sold as a built-in with the cart extra or optional. The link below is to the version that is on the cart.
American Outdoor Grill (AOG) L-Series 30-Inch
American Outdoor Grill or AOG is the 'discount' brand of industry giant Fire Magic. Like the Delta Heat above, this is an all 304 stainless steel gas grill made in the United States. It is also part of a complete line of outdoor kitchen products. This model can deliver 45,000 BTUs under 540 square inches of cooking space. AOG offers two lines, the lower priced T-Series and this, the slightly more deluxe L-Series. Anyone of these is an excellent choice in gas grills, but this model offers a few extras, like internal lights that make it a better choice.
Weber Summit S-670
This is the pinnacle of the Weber line. It has six main burners that can generate nearly 100 BTUs per square inch and there are 624 of those. There is a full rotisserie system with a pop-up rotisserie motor and rear mounted rotisserie burner. There is a dedicated smoker box burner and an internal sear burner. There is also a 12,000 BTU side burner. Altogether there are nine burners on this gas grill. It is largely made of stainless steel and has two, handle mounted LED lights and a fuel gauge (for those using this monster on propane). For those that want a Weber, but want all the Weber money can buy, this model typically sells for around $2,500USD.
Napoleon Prestige Pro 665
Like the Weber Summit above, this top of the line product from Napoleon is loaded with knobs. There are eight burners (one of the knobs is a wood chip drawer from adding smoke flavor). The five primary burners produce up to 60,000 BTUs under 665 square inches of heavy stainless steel cooking grates. There is also an infrared rear-mounted rotisserie burner and standard and infrared side burners. The construction (done in Canada) is primarily stainless steel, but like the Weber Summit has cast aluminum and powder coated steel parts. This is a complete grill in a single package and comes with most everything you will need except the food.
Sedona by Lynx 36-Inch
Lynx, aside from being one of the best of the high-end gas grill manufacturers, has also been one of the most innovative. The Sedona line represents their more financially accessible outdoor kitchen families. The 36-Inch Sedona grill is a powerhouse of a grill. The four main burners can produce up to 69,000 BTUs under 618 square inches of stainless steel cooking surface. This model also comes with a complete rotisserie system and quality construction. If you look at the specifications of this grill you will find that it is made with 201-grade stainless steel. This is a comparable metal to 304 stainless and hasn't proven to be any less resistant to corrosion. It is just less expensive to manufacture with.
Broil King Imperial XL
Broil King's monster Imperial XL grill is actually two grills in one. The main chamber has four main burners that produce up to 40,000 BTUs under 490 square inches of cast stainless steel cooking grates. On the other side is a two burner, 20,000 BTU grill with 240 square inches. Neither of these chambers is powered by infrared burners and are in reality, just standard grills. It sounds odd, but what this grill allows is variability in grilling capacity. The main chamber is large enough for most any meal or grilling task, while the smaller side presents a more efficient space for small meals. This grill also includes a full rotisserie system with rear mounted rotisserie burner and a small side burner. Comparatively, either the Weber or the Napoleon above presents a better choice, but this is still a great grill.
MHP is known for making old school grills. Actually, they have just been making gas grills like they did more than 50 years ago. But as all stainless steel gas grill gained in popularity, MHP introduced this model. As far as stainless steel grills go, this is typical. What I do strongly suggest is that if you buy this grill, pay the extra $30USD for the upgraded cooking grates. The SearMagic aluminum cooking grates are raised on one side and flat on the other, making them perfect for delicate fish fillets or vegetables, but also for intense searing. Aluminum is a fantastic conductor and grates like these are used by competition steak cookers all over the country.
Artisan Professional 36-Inch
Artisan is the 'affordable' line of gas grills from Alfresco. In almost every way, this grill is equivalent to the Delta Heat and the Sedona above. It is slightly less powerful, but not enough to notice and while about the same price as the Sedona, it is more expensive than the Delta heat. The Artisan is a very good choice in this price range (it sells around $3,500USD), but there isn't a lot to make it stand out. Of course, like the others, it is part of a large line of outdoor kitchen products.
Saber Elite 3-Burner Infrared
Pushing on the high price end of this list is the unique Saber Infrared Gas Grill. Constructed entirely (down to the bolts) or 304 stainless steel and boasting an amazing 18,000 BTU dual control side burner, this is truly an innovative product. The all infrared power is accomplished by focusing the power of three 8,000 BTU burners at a metal diffuser and inverted U-shape cooking grates. The fire is completely isolated from the food and the heat that cooks is what radiates from the metal. This gas grill is virtually incapable of flare-ups and is practically foolproof. Oh, and it also comes standard with a very good rotisserie kit and a thick and durable cover. The downside of this technology is that it produces more smoke than other gas grills, and not necessarily the kind of smoke that is going to flavor your food. It isn't distasteful, but not a benefit.
