I spent some time trying to decide between a cooker from the different outfits in Sikeston, MO. Pit boss grills (the one you linked to), Nolan's Cookers, and Cadillac cookers. I'll tell ya- my experience dealing with the first two was terrible! Those guys bashed eachother to no end- calling eachother theives, liars, no-good sunofabitches. The guy from Nolan told me that he spoke to a marine sniper who was threatening to kill the guy from Pit Boss.
It was too hard to cut through the bull****, and I ended up buying one from the people at Cadillac Cookers. They were a little (10%) more expensive but made a fantastic product without all the nonsense and wouldn't bash their competition. The rig has held up nicely over the first season and I can't recommend them enough.
