I've got the F.A,R.T. (Frankfort Arsenal Rotary Tumbler) I started off with the pins that came with it, and they are a bit of a pain to separate, I changed out to some larger pins, and it's been great! They have come out with a screen, you can put over the end, when you are rinsing, that makes the whole process easer. I know this is a WTB post, and I love mine, sorry not for sale!
