upgrade option
I could recommend having the old RCBS charge master repaired, but I would first caution you there are reloaders that sent scales in for repair and then almost forgot they ever owned them. The last go around after the first go around. My friend contacted his lawyer, before that he sent in two for repair, both were green RCBS types, after a long wait they were returned gray, needless to say his décor was green. Both machines were sent in to be upgraded, there was something about the difference in exchange and upgraded he did not understand. He sent the machines in to be upgraded, instead they exchanged them.
Complaint: The reloader thought the scale company was too insulated, something like a black hole, there was absolutely no information available to him between going in and coming out.
Some years ago I was asked to testify, seems there were a few unhappy customers that had an issue with engine rebuild and overhaul, then there was exchange. To shorten the story, I went by for a visit, after the visit they decided they did not want me to to speak on their behalf. The nice part? They ask me to notify them if the unhappy customers contacted me. The rebuilder lost.
