I recently picked up a Konica Auto S3 that needed a CLA. Many people suggested Greg Weber as the Konica god, but I found that his prices were very high and that his inventory was running low on spare parts. I ended up sending my S3 to Frank Marshman (aka Camera Wiz) in Harrisonburg, VA.
Mr. Marshman sourced a rewind lever for me and CLA'd my camera for a total of $60 (less than half of what Mr. Weber was going to charge). I received the camera less than two weeks after I sent it.
All in all, Mr. Marshman's services were excellent. He worked hard to return my camera to original condition and communicated well with me during the process. He didn't leave a single mar or mark on my camera from opening or adjusting.
I would not hesitate to send a camera to Mr. Marshman again. His work was top-notch and reasonably priced.
