I just got back from Saskatoon yesterday where I made a special trip to Cheng's Cameras. The man is a wizard with film cameras, completely taking apart my Yashica Mat 124G to clean the film lens, re-align the viewing lens, lube and adjust in under 4 hours for $55 plus tax. He has no web site but Google Cheng's and Saskatoon and it will come up. Call him. I do like Precision in Winnipeg as well but they have a harder time coming up with parts and "seem" to be less willing to work on older cameras.
