Frankford Arsenal Rotary Tumbler, it comes with pins. Fill it up, set the timer and let it rip. The Dawn and Lemi Shine is amazing. Add some heat to the brass for fast drying.
I use this as well. I use the "pods" that Frankford Arsenal sells for the tumbler. I tumble using hot water for about 2-3 hours, depending on how dirty the brass is. I rinse the brass using a 5 gal bucket and hot water, run them through a media separator then put them in a dryer that is essentially the same as a dehydrator for about an hour. Most of my brass comes out shiny as new, even some that were picked up in the dirt at the range that had been there for years!
