I see eastwood sells a vibrating tumbler to clean and polish small parts but then there is also the option to use a brass tumbler that cleans spent ammo casings. The eastwood one is expensive and the ammo one is cheap. Is there even a difference between the two? Any suggestions of a good one to buy?
