I also have the rcbs brass prep station with the reamer and although it does work, the money spent on the dillon is well worth it. In my opinion there is no contest. its not my intention to disagree with anyone that posted but I have tried almost all options (excluding the rbcs swager) and I have thought on several occasions that the dillon swager is some of the best money ive spent. I have never ruined a case with it. Just my opinion but i believe in it enough I felt obliged to reply. If you have alot of brass to do, consider it. Also do a google search on the dillon super swager and read some reviews? Have a good one
