If you want a good smoker that is easy to use but won't bankrupt you I'd go with a WSMC (Weber Smokey Mountain Cooker) I have one in my collection and love it. Portable, easy to set up, has good air flow, holds a good amount of meat and most of all is very effecient. I can pack it full of lump and it will go for about 10 hrs before it needs a recharge.
A good price. Get the Weber chimney also it's the mac daddy.

I also have a Brinkman Vertical Smoker that I heavily modified that works well. Out of the box it sucks.
Also a Brinkman Pitmaster Deluxe. Which was given to me and has been a good dual roll smoker grill.
And another generic Weber look alike that I have modified.
You can see three of them in use in this pic.
So I have just realized with all these my big cooker my gas grill and my car camping grills I have 8 total cookers. Wow! I think I have a problem.
