Right in the midst of a shoot my Retina IIIC died in typical Retina fashion--the winding mechanism died. Can fellow members of APUG suggest a competent repair service in North America who can fix a Retina. The meter, rangefinder, viewfinder and lens are in perfect condition and although the camera would make an attractive paperweight, I do enjoy using the camera. Please tell me your experiences and who you would recommend currently repairing Retinas. The cameras are a charm when working.
