I sent my iiic to Youxin about 2 or 3 weeks ago for a CLA. I want to say around May 31st? I don't want to say I received any special treatment, but I sent a simple email to him asking how my camera was coming along and he replied that it was there safe and sound, that he had a 2 month turn-around and if I wanted it sooner to just give the word.
I told him that would be great if he could do that, and the camera along with the Elmar attached was literally finished the next day, along with a detailed explanation of what was wrong with each item, and what he did to fix it. I paid and the camera was shipped to me next day. I should be receiving it tomorrow. Youxin is really a great guy!
Sorry to hear yours took so long! I don't think the wait has anything to do with how long it takes to CLA a camera, but with how many cameras he actually has.
