Before you can begin designing your custom gas grill enclosure you need to pick the perfect grill. Most high end gas grills come in an insert configuration that allows you to put it where you want it, but many are not a standard size so pick your grill first. Here I have listed the top 10 gas grill inserts over $4,000 to help you find the one that is right for you. Prices can vary a lot so make sure to do some serious shopping to get as much as you can for little as possible. Updated for 2013.
Kalamazoo Outdoor Gourmet, LLC.
The Kalamazoo K750HB is the custom insert version of the best gas grill in the world. It is also the most expensive (other than the larger 4-burner version). This is not, however a status symbol grill. I would certainly not like to see this sitting, unused on the patio of some hedge fund manager. There are products that command respect because of their name, but lack the function or capabilities to fulfill their promises. This is not one of those. Only people who truly know grills and outdoor cooking, know how good this grill is. It is designed for those who love to cook and are planning a custom outdoor kitchen.
R.H. Peterson Company
Fire Magic makes some very elegant gas grills that are very highly rated, especially by the people who use them. You'll also find the whole list of options available on these grills. Top quality stainless steel construction and a very good heat distribution system make these great units to grill on. This jumbo unit will grill anything you want.
Twin Eagles Inc.
The company Twin Eagles was put together by a veteran of the gas grill industry (actually more like a legend). Anyway, this grill is beautifully built with an incredible attention to detail. The engineering and precision make it truly one of the best gas grills on the market. Details like the hexagonal cooking grates that give you better surface contact to better searing are just one of the many excellent features of this unit
There are a lot of expensive stainless steel gas grills on the market. Most are well built of high quality stainless steel with welded seams and high gloss finishes. Alfresco is no exception to this. This big, beautiful gas grill is loaded with power and built to last. The even heat will generate high cooking temperatures and give you all you want out of a grill and with enough options to fit any need. The 82,500 BTU output of the main burners heats this grill up hot and fast. You can swap out one of these burners for an infrared unit, but with the heat of this grill you probably won't need the extra searing power.
Napoleon Gourmet Grills
This hand tooled grill is big. I mean big. The 850 square inches of primary cooking space is heated by over 100,000 BTUs. It comes with a whole host of standard features including internal lighting, full rotisserie systems and a wide range of options for your custom enclosure. Very nicely designed with great cooking abilities.
Vidalia Outdoor Products Co.
The Vidalia grill is unique amongst gas grills in that it is designed as a convection oven that allows you to not only grill directly of a high, intense heat (searing) but also to indirectly cook so that this unit can smoke, broil, bake, roast, and much more. This unit has two 40,000 BTU stainless steel (304) burner. Air is drawn in under this burner when it then circulates through the direct grilling portion, across the indirect area, then down and out through the other side of the grill.
Capital Cooking Equipment Inc.
This built-in version of the Summit S-650 gas grill is a large, six burner unit that offers all the advantages of a Weber Summit grill in an insert unit. This insert grill is unique in size and cut out so make sure you can fit it before you buy. If you can, then this grill offers everything you would want in a custom grill, but at a more affordable price than many other similar units (this one sells around $2,500). The full rotisserie system including infrared rotisserie burner. You also get an internal smoker burner, plus there is the option of a flush mounted side burner module.
Dynamic Cooking Systems
This is a beautiful grill with everything. While smaller in size it still offers everything including a full rotisserie unit, advanced ignition system, independent smoker tray and 3 25,000 BTU burners. It is also very cool to look at. The finish on this stainless steel grill is beautiful, but this is a serious grill that cooks good enough for the pros.
Thermal Engineering Corporation
Infrared Grilling at its best from the people who invented the technology. This unit has 555 square inches of primary cooking area with three infrared cooking zones. It also comes standard with a 60-pound capacity rotisserie kit, so you can cook that whole hog that's been taking up space in the freezer. Total 18-gauge 304 stainless steel construction that has storage space and good sized side tables. This is the grill for high temperature grilling using the latest in infrared technology.
Rasmussen Iron Works, Inc.
Rasmussen was one of the first companies to jump onto the Infrared bandwagon when the TEC patents ran out. Their line of Solaire grills are among the most powerful on the market and these days offer none infrared capabilities as well. These are quality, high-end, stainless steel gas grills that do everything one would expect in this price range.
