I (I think) want an offset smoker for burning wood instead of charcoal. It needs to be well built but I don't want a huge (yuge? ) smoker. I want one big enough to do a couple of chickens split in halves or a pork shoulder or a brisket flat. I don't want one of the flimsy ones that I've seen in the big box stores that are already rusty inside when they arrive from the factory. Any suggestions?
