I'm a propane smoker guy. I use one of these:
Masterbuilt Sportsman Elite 40" Vertical Gas Smoker With Value Kit : Cabela's
I added an eight inch cast iron skillet in the bottom above the burner to put apple chunks in. The only time that I have temp issues is when it's windy, then I just shield it with a piece of plywood and all is well.
I'm saving up for a reverse flow stick burner. It'll be a little while on that one, though.
