I used Midway vibratory with walnut hull for years, when tumbling with SS pins came along I switched to a Frankford Arsenal. While the SS pins definately got the brass sparkling clean inside and out I did not like having to dump the pins out of the cases nor prying the ones out of the primer pockets when they lodged there. I still use the tumbler, only NO pins just warm water, Dawn dish detergent and Lemi-shine. Gets the brass clean enough for my needs and I don't have to mess with the pins. I like the FA tumbler because it has a built in timer, just set it and forget it.
