Finally bit the bullet on a proper shutter speed tester
I kept putting it off because the good ones are pricey, but after messing up the timing on a Nikon FM2 last month, I had enough. Dropped about $350 on a brand new, calibrated tester from a shop in Germany. It showed up last Tuesday, and man, what a difference. I had a Pentax K1000 on the bench that was running slow, and instead of just guessing with the old 'listen and hope' method, I got exact numbers in seconds. Fixed a sticky governor I would have missed. It paid for itself on that one job alone. Anyone have a favorite brand for these, or is it pretty much all the same once they're calibrated?
