I am also thinking of buying a tumbler for low volume loading (~2000 rounds per year). Here are my thoughts/research so far. Looking at tumblers, I initially found this:
Berrys Brass Cleaning Kits
Looked like a good deal, but then someone on the CHL forums pointed out that Cabellas has the exact same stuff, just green.
Cabellas Case Tumbler Kit
Cabellas Rotary Media Separator
I can't by the exact same kit, but I get all the pieces for $78.98, verses $102.36. I may have to pay tax for Cabellas, but no shipping.
Then I got to reading some more. The tumbler above holds about 600 pieces. Then I got to thinking about storing all of the components, and I found this neat little thing:
Lyman Auto-Flo 2200 Self-Separating Tumbler
Auto separator, so I don't need the media separator. At $106.99, not that much more, and I get to clean 750 cases. But wait, for some reason, this one is cheaper, $104.99:
Lyman 2500 Pro Magnum/Auto-Flo Tumbler
1000 cases now. :) However, with the Lymans, no media is included, so the costs go up a little when I have to buy it. Also, the comments for the auto separators are not too favorable, so they may look cool, but they may be a gimmick.
So right now, I'm leaning towards the Berry's kit, as it includes all I need to get started. Anyways, just sharing my research and thoughts......
