Far as I know, the Parker Repro has the same ST problems as the original Parker with a ST. They used the same ST. Only difference is, you see a far higher % of ST Repros than you do originals with ST's. But lots and lots of people shoot ST Repros with no problems at all; most that have problems get them solved pretty easily and quickly.

Yes, I certainly advise DT's on a Repro. Perhaps the incidence of ST problems on Repros--given the fact that there are lots more of them than ICD's--is about the same as the incidence of problems with 470 series ICD's? In which case, a general warning to buyers about both potential problems seems well warranted.
