You should definitely buy the Grill Grates for whatever gas grill you buy. Evens out the heat and increases temp. None of the gas grills get really hot, unless they have the brazier burner (or whatever it's called). They cannot properly sear a steak. It's pathetic, because it's a liability fear, like crappy triggers on all modern guns.
The Grill Grates help a lot.
