I agree on the Char Griller. I wouldn't bother with it as a smoker again (too much work), but I love it as a grill. The biggest one, the Outlaw will set you back $200 - $250 depending on where you get it, but with a wheel modification, you can't beat them. Works nice as a rotisserie grill too. Just my .02 cents.
For my wheel mod, I put 3-inch stainless steel, rubber-stemmed casters on the shorter legs meant for the wheels that come with the grill. I put 10-inch semi-pneumatic tires on the longer legs, drilled holes and put in a 5/8-inch threaded rod for an axle. I also added a small metal handle on the side opposite the shelf to make pulling it around easier. Works like a champ. Tons of room in there!
