gas, electric, or charcoal grills

I agree that gas is your most versatile option. One cannot predict when a burn ban will be activated. For gas grilling, the Weber Q is hard to beat (I have a Q100). For simple gas burner cooking, I have an old green 2-burner propane unit I bought 30 years ago, no name on it, and other than one plastic knob it's all original. For charcoal, although I have one of those small Weber kettles and it works fine, due to space constraints I more frequently pack and use a folding EcoQue stainless steel grill (which seems to be discontinued, unfortunately).
