Some explanation about repair cost. All prices for the CLA service are fixed. It mean you pay fixed price, and total for repair never exceed this price. It mean you will never get bad surprice like "ahh, camera is very bad inside and I need more money for my hard work". If camera had a hidden problem - it's my problem now. You pay fixed price for getting working camera back.
There is only one exception - if your camera have a missing exterior parts. Putting new parts for FSU cameras cost nothing, but some exterior parts for Contaxes and Leicas may cost additional money. Anyway, exterior parts are easy to see! You will see for what you pay.
What included into CLA? I completely disassemble camera for access to all parts. Springs of curtains or optical parts inside RF- all will be cleaned. Old grease will be removed, and I'll glue all should be glued. And after deep cleaning I'll assemble camera again. That is why price is fixed. No matter what is actual problem was, I'll fix all problems during assembling camera back. With proper adjusting and proper lubrication.
