There is a place nearby me that has the same or a similar oven. They are ul listed, and that is the only reason he didn't end up with literally craigs acunto. The town would not allow it. As the owner has told me, he hates his oven, very unbalanced, hot spots etc. The dome is far too high. He has used the ovens at Amano and Keste as his comparisons. Not saying you cant make a great pizza in it, but I think they do NY a lot better, like a 3+ minute bake, everthing just slowed down. -Marc
