Somehow I missed this thread, interesting to see all these Austrians!
I guess because they are the most common, I ended up with two of the cheaper ones, a blue '72 Clubman and a Sears "10 SPEED" from '68.
Both turned out to be really nice-riding bikes, and I've put more miles on the Clubman over the last five years than any other bike I own.
Headsets seem to be somewhat of a weak spot in terms of quality, but the original (English!) bottom brackets seem top quality, requiring no adjustments after initial rebuilding.
