A UDS is a fantastic inexpensive smoker. However, IMHO, comparing a well made UDS to a well made reverse flow offset smoker is like... well, I dont have the analogy right now, but IMHO there is no comparison; not in volume that you can smoke, nor (averages being averages) in the quality of the BBQ that comes off. Even a gigantic UDS would have a tough time getting a hog on it; no problem at all with a good sized hog on the reverse flow offset...
