All I can say is that Don is a "stand up guy". And his work is indeed his reputation -- Excellent. Has always made things right for me.
That shop in Portland (OR?) will not be named, but I have had things returned as complete doorstops that were fully functional when they went in. They are not Leica techs, regardless of what someone tells you (or they say). I'm not trying to tarnish their reputation (much), but I would not recommend them for any
Leica service. I think they might be fine for recent Canikon DSLRs.
Hope you didn't get fired
