Smoking is great fun and my new favorite hobby when I can't hunt or fish. Just did a big batch of jerkey last weekend. Need to finish of some salmon soon and do a pork butt as soon as the temps come up a little for overnight smokes. It is hard to get some of the electric smokers up to temp when it is as cold as it has been around here lately.
I started with a Master Built and got a Bradley original last year. Now I upgraded that with an Auber control for long slow overnight smokes on brisket and pork butt. Not very trad of me I know, but for long smokes I like technology to baby sit it so I can do something else for a while like hunt, fish, or sleep. I highly recommend the Bradley forum for anyone using an electric smoker and just for smoking in general. There is a lot of info there. You can rig a Bradley to cold smoke no problem with an off set setup on the smoke generator.
