Based on these mixte discussions I started looking around and I found one on Craig's list not 10 miles from here and went up and rode it the other day.

Though the ad says it's in good shape, the owner's perception of "good shape" and mine are not the same. It was a classic Raleigh mixte, but was just too small for me to ride. Plus it needs new tires, new chain, new brake cables, and the rear wheel needs trueing.
They have reduced the price to $50, but even if I did al the work, I'd still have a bike that was just too small. I had to give it a pass.
Sigh,
