After browsing my options, I settled on Paul Barden for the repair of my Kodak Retina IIa. In short, the service was excellent, and I am a very happy customer!
When he was working on the camera, he emailed out an update and offered me a few options when it was revealed that the film counter spring had snapped. The price for a spring salvaged from a parts camera was very fair, and the price of the work as a whole was fair as well. After having watched hours of Chris Sherlock's videos, I had no desire to attempt the CLA myself, and Paul's pricing and quick turnaround made me a very happy customer. Return shipping was quick and securely packaged, and the camera performs excellently and looks great.
