I just got my M9 back from Leica NJ. Sensor replacement and overhaul plus shipping plus tax = $1,700.00. Took 3 weeks. The process was very smooth. I got my done because as Leica confirmed, the shutter count is 3917. I did the calculation when I bought it 2.5 years ago from National Camera that it had 1747 on it then. Now I need to use it. Too many cameras M8, Z6, D700, etc.
