Teeters - I don't know what size you're looking for, but the "Large" BGE, 18", is plenty big enough. I know it's smaller than the 22" Weber, but it seems a lot more effective. The whole thing gets hot for starters, not just the area under the fire. Then there are a myriad of racks you can get for it to maximize the space available. Nearly all the accessories (and there are many) are sized for the Large too.
I had various 22" Webers of the years, culminating int he Weber Performer, which was a great piece of kit. But it can't compare with the 18" BGE. Of course the BGE is more expensive, but my point is that unless you have a family of 12, the 18" BGE is sufficient. The Extra Large just wastes coal unless you're cooking for the Mess.
