I have a stainless pin tumbler that I made for over 350$ with a 1/2 hp motor, ball bearing industrial rollers and a drum that can hold almost 2000 223 cases, it works, but it's a hassle, it's heavy, and then you have to dry brass, etc etc.
I like it to clean super dirty brass, but just to polish clean brass, it's a hassle to wash, rinse and dry all that brass.
I think both cleaners have their pros and cons, and the best is probably having both.
I want a vib. tumbler just to polish clean brass, and I think a vib tumbler is better than ss pins for that.
