Thanks guys good stuff, it looks like you all use the same type of devices to cold smoke. I'm mainly thinking of using saw dust do to the fact I have an endless supply of it. Does one of these work better with saw dust? It's looking like the A-maze-n might be the route I may take. The things i saw on the net used aquarium pumps to blow the smoke in to cook chamber. I guess those are just expensive toys that aren't needed.
