Our two M3s (mine and of the friend of mine) are on their way to us right now from Youxin. Were a real beater cameras, non-operational, rough-looking ones. They received a premium treatement by Youxin, a necessary repair (like shutter curtains replacement, lens mount replacement, some internal bits, a major CLA and new external cosmetics (a new vulcanit covering). All that for very reasonable price, considerably lower then I was quoted by other, well known and respected Leica repair/CLA masters in US. I'll be reporting back upon their arrival, but as for now we're more then satisfied by his prompt service, reasonable pricing and excellent communication.
