I have a Dillon and MEC, a friend has an RCBS, and we own a lot of RCBS dies. The only parts either of us have ever paid for was the wad fingers for the MEC, the chain and spring for the old style primer tray on the MEC (I switched to the new style tray and can't wear anything out), and a screw on cap for an RCBS bullet puller (some idiot slammed the wrong end down on the bench - anyone know how far those plastic pieces can fly). The only reason we paid for that part is that we bought it locally. When we were ordering some other stuff they we joked about what we had done, and they sent us two more free to "idiot proof our shop." Dillon has even sent us packs of extra stuff we didn't ask for, because it "usually wears out at the wrong time."
I still say that my experience with anything in the shooting industry is excellent! If we could get other's heads out of their PC holes they could all learn from the industry we love.
