Sorry the road show was such a bust. I have never heard of them doing demos, but I've also never heard of them not starting with so little stock. I imagine that was some kind of screw up. I've been wondering about the price increase as well. My guess is that with the divide and conquer rig included and their growing following, they don't need to to compete with the BGE on price as much as they have in the past.
As for the Pit Boss, I am sure it would be fine. Although they say it is a 24" grill, the inner diameter is more like 22". That may be a plus not minus though. Around here they start getting marked down for clearance by July 1. I think last year they were marked down from $599 to $399. I do not need another cooker, but at that price I was tempted. I have seen a post from someone who has already bought one there this year so it appears they will be stocking them again. It also appears the Visions are back at Sam''s Club again this year ($549 online). I like the KJ, but the Visions are looking good for almost half the cost.
