You will never get good smoke from a pellet smoker. If you want that you need something better. Look at
American BBQ Systems The are a bit more than pellet smoker, but they are made locally, in Olathe, and they are an awesome company. I bought one and the president of the company personally delivered it to me. I can fill it with charcoal and wood chunks. Set the dampers and it will burn for 8-10 hours @250 F with very little adjustments. Just my $0.02 worth. They do have a wood pellet option, but I haven't heard anything about it. If you want a quality smoker be prepared to spend over $1000 for it, probably more now.
