Thanks for the feedback! I'm usually about a 52, depending on frame geometry. I need a top tube that is in the neighborhood of 52.5-53 cm. I'll be looking at closeouts in addition to secondhand, since we're approaching that season.

I hadn't thought of Bianchi steel bikes, but there is a dealer nearby so I'll check them out. Love the classic styles.

Fortunately, I live in a very bikey city- Portland OR- so there are several LBS and lots of people reselling.
