RCBS primer tools...
Dirt Digger--I set up a bud with the RCBS bench-mounted strip priming tool--his works slick. We also got him the loader for the strips, so he could re-use the strips and not have to buy the primers pre-inserted. That gizmo works slick too.
If you're talking hand-held priming systems, I use the Lee Auto-prime and it also works slick. The RCBS hand-held is sturdier than the Lee (and more expensive) but has a good reputation.
