Yup, I have to agree with Bill ... having spent the last few years treasure hunting for great deals on cameras and shutters I've finally come to the realization that they're pretty much useless if they're not accurate. No point in using your light meter, figuring out exactly what shutter speed and aperture to use if the shutter doesn't actually work at the set speed - you'll never get the results you're after ... or at best it's a crap shoot, might as well just use a point and shoot.
My local tech is a bit cheaper than $100 I think, but for classic medium/large format shutters APUG's own Carol Flutot Miller is the one to talk to. Can't say enough good things about her.
