So I finally got a lead on 55 gallon, unlined, steel drums for $20 each. I've been looking for a while and was thinking about picking 2. Considering how everyone seems to love them it seems it might be worth it if the consensus is they end up with multiple down the road. I planned on one day competing and I figured I need at least two smokers but maybe my 18" WSM and 1 UDS will be enough.
