Like Erik said, Ted. The M6 (including the TTL) is still the 2nd most produced M body in Leica's history. On the internet, of course, you hear about problems more than about reliability. But even if you see, say, 10-20 failure reports (which I doubt), it means nothing because of production volume. Just compare to Hexar, Bessa, ZI and M8 failure reports and compare to their production volume.
Plus, you had an M6 with the more robust Leicaflex rewind. This must be the most robust Leica out there, and probably the most robust M mount RF ever. Zinc tops might be ugly and not brass nicely, but they don't bump as easily. Steel gears might feel rougher but they are tougher, etc.
Why did you sell that M6 ?
I know all this might be tongue-in-cheak from you, but I also know you well enough that I believe you are not trolling. Probably just looking for the best body for your ASPH 35/2. So there, get an M6/M4P with Leicaflex rewind again. 🙂
