I've got a large BGE and use a FireBoard temp control system on it. I spend very little time watching over it. If you don't have a temp control system, you have to keep an eye on it during at least the beginning of the cook, but once you get used to it and get dialed in, there's not much babysitting. Not saying there's anything wrong with pellet smokers either though if you go that route. Lots of ways to skin and smoke a cat.
