The big draw back is the size. There are two sizes available. The BGE is the most recognizable brand, but they originated in Japan, and are known as Kamodo cookers. all basically the same. Heavy ceramic chamber that holds the heat and provides a constant temperature. The one big BBQ guy that always cooks on them is Ray Lampe, aka Doc BBQ. I beleive he is sponsored by them. But, he only cooks for competitions, has several going at one time (one for each category), has a helper, and is only cooking for the judges (6), not crowds. It can be quite a feat trying to maintain 4 fires at once. I'm still looking for a used 8' pit in good shape because I'm sick of maintaining 4 fires due to lack of cooking space.
If you're only going to cook for a small amount, a WSM or bullet type smoker might be more suitable for you Jeff. They're less money than the BGE, and you have 2 cooking levels. You can do 2 shoulders on it no problem, one on each grate. I have 2 Bullets, and 2 homemade 55 gallon drum smokers. I've never had a problem with any of them, except for keeping an eye on all the fires at once.
In the 55 gallon ones, I line the bottom with fire bricks to aid in the heat retention. I just did 2 shoulders and 2 butts in one the other day for the NYB BOD meeting yesterday. 11 hours, no problem.
Hope this helps you out Jeff. E-mail me if I can help you.
