I agree with the poster who recommended Weber Grills, I have a weber that Ive had for 10 years and is going strong still. One thing nice about the webers is that for about 80-100 bucks you can replace the grates, flavorizer bars and the grill is good as new IMO.
Once a year (usually in the spring) I take my grill to the car wash (do it yourself kind) spray a whole can of oven cleaner on it blast it with the pressure hose, works great.

My brother in law just gave away his 1000 dollar Jenn-air because it didnt cook as well as his 400 dollar weber
