Got my large big green egg a couple of weeks ago so I'm a noobie. My question is what kind of pizza stone do I want? Ceramic, earthen ware, stone ware? I know I could buy one from Big Green Egg but I was wondering if something was better or less expensive. By the way this is a pretty neat site. I'm sure down the road I'll start to contribute. But right now I'm still learning the Egg.
