Concur! I used to be intimidated by the process too but after some research and practicing on throw away cases I found out how easy it was. I shoot a .257 Weatherby and at about $1.50 a case for Norma brass I am looking for anyway possible to keep them in service as long I can.
I do not have any good method. After shaking out the water from each case I just let them air dry for a couple of days. It takes two or three times to shake out the water. The one thing not to do is put them wet into your tumbler with media. It cloggs up inside the cases and then you have to take a pick and pick it out.
