I have the Classic Joe, which is the same size as the Large BGE. Price wise it was slightly less expensive. Quality has been great, and I have been pleased with it. I cook on it about 2-3 times a week. I use my pizza stone on the smooth side. The color was the driving factor for me, we have the red one, although I wanted the black one. My wife wanted the red one, and was completely against the green of the egg.
I cant see the video here at work that the OP posted, it is blocked here. If I had a need for one, I would buy another KJ again.
