My 2 cents, no question a guy like you should strongly consider a Weber Smokey Mountain (aka Weber bullet). As has been stated, the temps are very stable and for the smallish footprint, you can fit a lot of food in it. Check out the Virtual Weber Bullet for info on capacity and techniques.
As you can see, the WSM has an almost cult like following (myself included) and for darn good reason. It turns out fabulous succulent food on a consistent
basis. I think I can reasonably say it's a purchase you'll never ever regret, especially after you pull your first meal out of it
BTW, the smoker I had before my bullet was a Brinkman and I hated that thing. I put it out on the curb with a "Take Me" sign on it and it sat out there for a week before the garbage man came and carted that no heat holding piece of %$@* off of my property.
