My first road bike I bought used at a local beach bike store. They had a used Trek 2000 47cm bike. I test road it, and they fit to me the best they could. Ended up buying it for $400. I'm 5'0" so you have an idea of sizing. I just bought a Felt F5 48cm bike which I love, love, love. Like one of the others mentioned having the Trek has made me appreciate the F5 that much more. I'm actually making the Trek into more a commuter/errand type bike. The Specialized 44cm bikes also fit me. Before I choose the Felt F5 I was also looking at the Specialized Ameria (44cm) and the Trek Madone (47cm). Felt also has the ZW line if you are interested in looking at that brand.
