What I've found out is you need to buy a smoker for smoke'n, and a grill for grill'n. Those green eggs get dang hot, from what I've heard, but I wonder about the low and slow at 225.
BGE would be great for pizza, though.
You only live once, get it and if ya just don't like it you can sell it. Might take a hit, but I think it would be fun to cook on one.
OR, you could buy me one, Bill, and I'll tell ya if you made the right choice.
You could then thank me later.
