RE: Case tumbler, corn cob or walnut media?
Check out the Lyman 1200 auto flow. I really like the one I have. All you do when your done cleaning your cases is put a pan under the exhaust port and pull the plug and let it run. It automatically seperates the cases from the media. I like the walnut media with Lyman's Turbo Brite brass polish added to it. Buy the walnut media at Pet Smart or any other pet stores it is a lot cheaper.
