I'd like to start making pizzas on my kettle, so I'm looking for suggestions on the best pizza making accessories. Is the Gourmet BBQ System w/ pizza stone all that I need or should I go all out and get something like the kettle pizza kit? I'd like to get the Gourmet cast iron grate for searing, so if the pizza stone for that works well, that would be great. If it will just make me wish I had something better, I'd rather just buy that first. I've seen several pizza pics on here, so please share your experiences. Thanks.
