I was able to get everything I needed at the local Menard's and Ace Hardware stores. I already had a step drill bit, so I have less than $50 in my UDS, including the drum!
My UDS is my first smoker, as well. I'm on my second smoke today. The first one was a butt last weekend that was a huge hit. I have ribs on today. I'm not so sure about these. I got a rub recipe from the 'Net and I'm reserving judgement until we eat.
