What features and accessories do you need?
Shelves and storage space: You don't realize how handy it is to have a flat surface next to your grill top until you are trying to juggle plates, hamburger buns, condiments and a spatula in your hands all at once. As well, you can store tongs, scrubbers, and other supplies in a cupboard beneath the grill.
A thermometer. Most modern gas grills all come with a mounted thermometer, which is a safety feature as much as it is useful to the cooking process. Check out customer reviews to find out more about the thermometer of the gas grill that you're planning to buy and prepare to buy a separate digital thermometer if your grill is on the cheap side - it may not be the most accurate.
A cover. Covering the grill when it's not in use is absolutely crucial to its longevity. Make sure that the cover is unlined and synthetic - flame retardant polyester, durable nylon, and vinyl will do well. Always make sure that the barbecue is fully cooled before putting the cover on it.
