Mamiya 6/7 Rangefinder Calibration.. Who Does it?

I was thinking about sending my Mamiya 6 out for a calibration since I now have all three lenses. I'm looking for recommendations for places that will do a great job calibrating my rangefinder at a reasonable price.

The only two I know of now are Precision Camera Works in Chicago and Mamiya USA. Don't know prices for either one though.

Mamiya will do it for around $65 last time I checked. Call MAC up and get a quote just for that.

Should be in the same ballpark for Precision Camera Works as for Mamiya as referenced by Andrew. I can vouch for PCW; if you contact him (google for his website) be sure you find out his current work backlog to avoid disappointment; he took a bit longer than I'd expected but did the work right.
