Been thinking of switching over to the shiny side and my wife is asking for Christmas suggestions. What are you guys using? Thumler's tumbler B, Frankford Arsenal, other?
I was just at PAuto looking at motors for a DIY build
I was considering a Thumler's B, but couldn't spend the $... So, I found a used treadmill for free from the local buy-n-sell. I cut out the middle of the frame and welded it back together again to end up with a heavy duty, variable speed tumbler. A piece of 6" PVC found in the scrap pile was made into a 2 gallon barrel - 10 lbs of media does a nice job on 300 rifle cartridges. Purchased parts: PVC cap, rubber cap, roller ball and replacement rubber feet cost me about $33.
parts:

barrel with speed bumps:

frame cut and re-welded, with roller ball and scrap UHMW to keep barrel from rubbing:

ready to tumble:

first load, towel dried then out in the sun (do not let the Mrs. see this pic of her drying rack):
