I've recently started using the stainless steel media, and I couldn't be happier. Once fired brass will come out spotless, inside and out, in less than 2 hours. I tested it on some of the worst range brass that I could find, and in 4 hours they looked like new.
The upfront cost is pretty high, but dish soap and water are the only supplies that you need going forward.
