The replacement of the grills on a barbeque really depends on how often the barbecue is used. I find that we have to replace our grills usually once every two years because they begin to rust and the flames tend to flare up when barbecuing.
Most major retailers in your area will have grills and barbecues for sale. Wal-Mart, Target, Sears, Home Depot and Lowe's all carry grills just to name a few options.
Old fashioned charcoal barbecues are available in walmart stores. Other types of grills like gas grills are also available for better efficiency than the charcoal barbecues. Also, charcoal barbecues create more smoke than the gas grills.

You can find charcoal bbq grills at sears, or the home depot. They have a pretty decent selection there for grills, but it ranges from $200-$500. I reccomend that you go home depot, since its for convienvce and most likely closer to your house.
Yes, they are pretty high up as far as cost goes and they look quite nice as well. They are durable and make for really nice grills for summer barbecues.
No, electric barbecues do not have to be plugged in - they are constructed to be portable in many cases and if you look at the pictures you'll never see a plug in sight.
