Sure, there may be three sizes in the Echelon Diamond Collections, but the E1060 is really the only one you should care about when it comes to outdoor grilling. Made by Fire Magic, this barbeque is crafted from high-quality stainless steel, which resists oxidation and corrosion, and comes complete with heavy-duty, stick-resistant cooking grids. Promising more room than any other brands, you'll be able to cook an entire meal in the E1060 at once. Plus, with a heat range from 200 degrees up to 1,000, you can sear a steak or even bake dessert in there (you probably won't, but go ahead and test it out). The safety knobs are back-lit and the view window lets you check out how your food is doing without opening the lid. The E1060 comes in portable ($11k-$14k) and built-in versions ($8,500), but we definitely think the built-in looks much sleeker and far more professional. Besides, who wants to wheel their grill in for backyard parties when you could have an outdoor kitchen?
