I broke my first pizza stone the other day and am in the market for a new one. I broke a Pampered Chef one (broke on maybe the fifth use...temp around 650) and noticed on the site that brand has a tendency to do so. Can some folks chime in with their pizza stone experiences and what brand they would recommend for a new one? Thanks in advance and for someone like me who received a BGE for Xmas, this site has been an invaluable tool. You guys rock!
