I too was looking for a "good Pizza stone " My wife when she was out picked up the 16.00 one not really knowing there are different ones.
When I opened it I thought it was gonna break one the first use ... I have had it for 2 years nows and it works good !1 .. When this one does break Ill look at the nicer ones ... But thought Id chime in on my expererience with a cheaper cost model.
