Good info here including this: “Choosing a gas grill: Ignore the BTUs and heat for the most part—unless you really need to cook a whole bird or roast this weekend, most grills have got your steaks and burgers covered. Consumer Reports’ blog recommends bringing a magnet with you to gauge the quality of steel used to contain the heat. If the magnet sticks, it’s likely a cheaper grade that will rust more easily. Feel free to give a test model a few shoves and shakes, as an unstable grill is a recipe for serious problems.”
