Don't really know what I am looking for, but this seems to be a good compromise on price and quality. Also, what media do I use? I am thinking of 1/4" stainless steel bearings, but when I started looking, there are several different "mixes" of different stainless steel media for the tumbler, and I don't know if these have any particular advantages for snuff grinding. Just wondering if I am on the "right-track". Thanks.
