That is within the perfect size range for smoking.

My smoker is made by Masterbuilt and retails for $160-$180...not to bad considering how much use it gets. It holds temp between 200 F and 250 F. I've never tried lower (for that I'd use my Big Chief) or higher temps (that would be a job for the grill). The 225-250 range is where you want to be anyway for pork shoulder, ribs, turkey, chicken, brisket, etc.
