ditto http://www.barbecuenews.com/forum/topic.asp?TOPIC_ID=9861 one of the best places to start. Lots of options out there to fit your needs. Another item is to see the main page and find some competitions near you and go visit talk with the cooks and see what they like and dislike about their smoker. Some of these conversations can be quite interesting. I did this for a long time before making my decision to purchase a Stump.
I will try to help ya with your choices. I've had most the smokers out there at one time or another. Got 23 now. Give me a hollar or an email when ya have a few minutes. My cell phone direct is 1-713-818-2263/ It's on all the time./
