Hello, my father has an old smoker that he uses and is to cheap to buy a new one. He has great luck at times and burns things the rest of the time. He uses a small single burner electric hot plate with a cast iron skillet as the wood tray. I want to buy him a new one, but I see charcoal,electic,propane, what one is the easiest to use? I have read that the propane ones are hard to keep the temp. low enough. Please I need help fast before the holidays. I should mention that cost is a concern what can I get in the $100 range? Thanks everyone for helping me out with this, Victor
