I trim my high volume stuff on a Giraud, and my precision stuff on a Wilson/Sinclair. I use a cordless drill to power the tools like primer pocket uniformers and flash hole deburring. A friend uses one of those Harbor Freight drill presses for his case prep, but he wired a sewing machine foot control pedal to it so he could slow it down and use both hands. I always kinda wanted a mini-lathe, but I really don't have room for one.
I posted a thread last summer about having a case prep party. Several of us got together and divided up the work, where someone did one of the steps in case prep. IE, flash hole deburring, primer pocket uniforming, primer crimp removal, ect. One of the guys brought his case prep center and it worked fine. After trying it, most of us liked the cordless drills better.
