For the most reliable and longest-lasting gas grills, expect to pay $500 or more; you'll find the best build quality and most durable components. In this price range, you won't do better than the Weber Genesis E-310 (Est. $700) , which garners the highest ratings and greatest number of positive reviews from pros and consumers alike.
The Genesis E-310 scores well in one professional test of gas grills, winning high marks for both convenience and grilling at multiple temperature levels. In addition, about 200 users posting comments to Amazon.com give the Genesis E-310 an average rating of 4.7 stars out of 5. The grill also earns a high rating (4.8 out of 5) at HomeDepot.com, GrillsDirect.com and Lowes.com, with about 100 to 200 reviewers each. Comments are nearly universally positive, although we read very isolated reports of uneven cooking or slow preheating.
Users say the Genesis E-310 is nicely sized, with 637 square inches of cooking space and durable, thanks to its porcelain-enameled shroud and enameled, cast-iron cooking grates. They also say that it's easy to clean and easy to use, thanks to features that include a built-in thermometer, heavy-duty casters and an electronic ignition system. It can be powered by propane or natural gas and users report very few flare-ups. A stainless-steel model, the Genesis S-310 (Est. $850) is also available.
If you're looking for a grill that offers more in the way of versatility and build quality, reviewers recommend the Genesis S-330 (Est. $950) . It delivers the same heat output (38,000 Btu) and has the same-size cooking space as the Genesis E-310, but for the extra $250 or so, you'll get a side burner, a sear burner and stainless-steel construction.
The Genesis S-330 earns a recommendation in one professional test of grills and an average rating of 4.7 stars out of 5 from about 120 Amazon reviewers. Owners posting feedback to GrillsDirect.com, HomeDepot.com and Lowes.com give it an average rating of 4.7 or 4.8 (albeit with fewer reviews than the Genesis E-310 garners). Most users rave about the sear burner's performance and say the model is easy to use, although some say it could be better at indirect cooking (when food is not placed directly on a flame). You can save money by choosing the Genesis E-330 (*Est. $800) , which provides the same features but has a porcelain-enameled construction instead of stainless steel.
