The Claud Butler that was on eBay apparently didn't sell or even attract any bids, at $275 asking, and is now re-listed....with a higher opening. Interesting selling strategy.
Seller has imperfect feedback and doesn't inspire confidence from his description, but if it was possible to pre-inspect and pick up the bike personally, it could be a good deal, for a small-builder bike.

Most companies simply didn't make a mixte version of their bikes above the low-middle range. For example with Miyata the best mixte was the model 210. A mid to late 80s 210 would have a double or tripled butted cr-mo frame, 'managaloy' fork, cantilever brakes, a triple chainring, and might be as light as 25 lbs. Not exactly a racer but a nice bike. They don't turn up often, but something like that might be offered up cheap as 'an old women's 10-speed.'
