Been lurking awhile, and figured I'd ask a question before I buy this thing. I think they're regularly $74, and they're on clearance at my local Wal-Mart for $40. Given that I have no smoker at the moment, is that a good buy? I understand it'll need some mods to get it to right temps. I probably don't have the patience to build a UDS. My last smoker was a Rival Electric KC Smoker. I was less than impressed. Thanks in advance!
