Ok. This for serious pizza-holics. The Old stone Oven brand pizza stone has been regularly rated number 1 over the years by test kitchens. I have it and love it. It fits in a normal oven and can operate no problems at high heat..up to 2000 degrees but 500 is more then enough. I've had many brands (pampered chefs etc) over the years and this one just won't crack. It is also great for baking bread on too. Normally $50 and now $10 off for $40 with free shipping. It's the best price I've seen on it.
