hi my buddy bought a frankford arsnel rotory tumbler it works quite well we ran some old military 30/06 brass that was black thru it to try it out 1 hour the inside and outside were like brand new , but the primer pockets still had a little stuff in them. we gave them 1 more hour (2 total) they came out better looking than new it came with 5 lbs of pins they miced out at .039 dia it is gear drive has a up to 3 hour timer the drum is 7 quarts I had already started to build my own so will continue that project ,why buy one when you can spend twice as much money building your own. but really if you want to buy one these are nice units
