I'm thinking about buying a Big Green Egg. Does anyone own one of these? I can buy the large with the nesting cradle and the fold down shelves for $609 plus tax. It looks really cool and it may be my all-in-one griller/BBQ/smoker I've been looking for. Anything special one should know about it? I'll be using for ribs, chicken, steak, roasts, smoking fish, and even maybe a pizza or two.
