I also forgot to mention the pizza stone itself. Get a good one! The Pampered Chef ones rarely make it more than a couple of cooks before shattering...ask me how I know. BGE, Primo (which I use) and ceramic grill store sell nice heavy ones. I have also been messing around with a product called the
Baking Steel. I have been happy with it, although you do have to shorten your cooking times. One other plus factor is that it makes an awesome griddle for burgers, breakfast, etc.
