I am on the verge of buying a Big Green Egg, and I am having trouble deciding between the medium and large sizes. Space on the deck or in the carport really isn't an issue. Cost is, but perhaps over the long haul it is worth it to have the larger one. My wife and I do not do much entertaining except when the kids come home to visit, but we do tend to grill a bunch of stuff at one time and freeze it for handy weekday meals. I'm assuming the amount of charcoal used is not all that greater for the large, but let me know if I'm wrong. With the medium, I guess I could grill multiple batches on the same load of charcoal, right?
