I've been looking for a good hand priming tool myself; just sent back two of the RCBS models the with universal shell holder. The new Lee square tray versions are sorry compared to the old round tray "dangerous" models. Mine finally wore out.

In the interim, I've been using my Co-Ax on-press system for rifle cases and the on-press setup for handgun brass on my Texan turret. Perhaps to get a good hand-held priming tool now, one may have to go with a good one like a K&M or 21st century.
