Reloaders that have had case prep centers the motorized type which one has the most longevity and has worked the best. I won't be doing any military brass that needs to have the primer pockets done. Use would be chamfering, deburring, and primer pocket cleaning with a brush or the little flat blade scraper. I think as I've gotten older I have a little more arthritis in my fingers. Just looking at making some of the operations easier. I really wish I could get one of the super expensive trimmers that do not leave burrs. I also been looking at the RCBS dedicated trimmers that do the entire job but then I may be in it for more money with those. So anyone that has some opinions on these would like to hear them. Currently reading reviews on the RCBS and Lyman. Will also look at others.
