I have a Nikon F4 that has a bad ribbon cable connector so the viewfinder displays flicker on and off. I'm certain that all that needs to be done is to have the front of the camera taken off and a new cable connector installed. I don't want to spend $200 for it, though. I don't mind sending it anywhere in the US, but it's hard to know who you're dealing with or choose between shops when you are just dealing with them over the phone. Has anyone had good experiences with a particular camera repair business or care to recommend one that does good work at reasonable rates?
