I’ve personally had good experiences with ICT. Jim has worked on several items for me in the past few years. Yes, he’s buried in work. The $50 assessment fee, credited against the final bill, tends to minimize the tire-kickers.
No competent tech is likely to quote a firm price to work on a 50+ year old camera without first examining it in detail to understand the time, effort, and parts that will be required. There are too few techs and too many cameras needing repair, nobody wants to undertake something that could turn into a real hassle. That’s just how the repair market is today.
