I sent my dinged up ex-U.S. Navy Rolleiflex 2.8F to Jim Holman of International Camera Technicians in San Diego. ictcamera.com. Shutter blades hardly moved, the shutter speed adjustment wheel wouldn't move due to bashed in front plate etc. I got it back in 5 weeks and it's been working perfectly. He also found bent springs, non-OEM springs(Navy jury rigging). Called me to discuss options. The parts alone came to $173. The total was $500(included CLA). He charges a $50 estimation fee, which is fair since he has to take the camera apart and examine it. Most repair folks hide that in their final cost. If you agree with the estimate it's incorporated into the final bill. If you don't it's used to put the camera back together and for return postage. Right now, he's accepting work and I just sent him my Mamiya C220 that lasted a roll-and-a-half before the automatic frame stop went out. If you go to the website and look under medium format it says he repairs rolleiflex with no specific models. He may do the SL66 also.
