I had a real smoker before. Used to smoke full turkey breasts in it... awesome. Have to say though, it was a little P.I.T.A. to use it. After a while it just sat there in my garage getting in the way all the time. finally sold it on sidewalk sale for $10. It was a steel cylinder, with a "L" brackets located at several levels to support the charcoal rack and bowl, the food racks, legs and a lid with a small vent. Very simple construction, could easily be home made if you had the racks and a steel can of some kind, a few L brackets, a few self tapping sheet metal screws... You're good to go. steel trash can would work great if they still make them. The down side is that the smoker was so cheap to buy in the first place (Wal-Mart), it prolly wouldn't be worth the effort to DIY it unless you can't find one to buy.
