I had an RGM 300 and hope to own another one of these days. I bought mine used and owned for probably 6 months, maybe a year without issue. I had limited dealing with RGM and they were all good but I do not know their reputation for service issues. They make a nice watch.
Stretch, the Speedy is a nice watch. I owned one for a while but it was a 39mm and a bit small for my tastes. I assume you are looking at the 42mm version.
