Velo, unless you buy USED, buying a bike sized by the frame just about doubles the price -- then you get into fitting the guy to it. Somebody who rides like the guy she's describing WOULD be a waste on a better bike. Most likely, he's the type of guy who thinks you're SUPPOSED to put both feet down and stay seated at a stop, and sit perfectly upright while pedaling.
I guess short people can't learn about bike sizing, eh? I'll let my co-worker (5'9", MTB racer and mechanic) know he's disqualified.
