I just called MAC today. $308 to refurb my newly aquired Mamiya 7. My question is, do I need it refurbished totally, or just get the rangefinder replaced for the 7II finder and have it re-aligned? There seems to be no issues with the camera, but it's used and while not abused, has seen some use. Do I really need them to replace all the springs and stuff in it? I think perhaps MAC is trying to upsell their service.
