Buy a Traeger. Best damn smoker/BBQer out there. I smoke it for 3 or 4 hours then turn it up and let it go. Once the bird gets a nice golden color, I tent it with foil. As long as the hopper is full of pellets, I'm good. I've used apple, cherry, alder, and other pellets in the past.

Way cool smoker for fish, too.
