I have a Bradley as well. Luckily it was a garage sale find for $50, because those pucks don’t come cheep. Still trying to nail down a good bacon brine, but each batch gets a little better. SWMBO got me the cold smoke attachment for Christmas. Have not tried it yet.
We obviously have different check books, because that is more than spending a little to me! 
One of the local maple syrup producers has SS 50 gallon barrels which he will sell a few of each year for $75, I have been considering making a smoker out of one, probably could do it for under $100 after adding the necessary grates/racks, cutting a hole or two, etc.
Thanks for the review of the Akron, Mike, those have been on my radar for a couple years and I’ve been considering purchasing one. I collect grills/smokers like other people collect baseball cards.
If I’d had access to sub-$100 55 gallon food grade drums I wouldn’t have bothered with the PBC. All said and done, a UDS was looking to cost me around $200, and still be larger/heavier than what I was looking for.
