Looks like too much money. Look around locally for barrels. I bought some locally that were bare steel inside with a removable liner, and paid 15 bucks apiece. Spent about 60 bucks for other parts at HD. Now for less than 100 bucks and a few hrs of my time, I've got an amazing smoker which I would put up against any WSM.Yeah, I've heard nothing but praise for them.
Also, anyone interested in their own UDS should take a look at this ad on eBay:
