Thanks for the replies so far. When I left the LBS, we kinda settled on the 52cm, but he had to order one in from another store location because the one pictured was too expensive for my budget. And unfortunately, the 54cm bike pictured is cheaper than I wanted to go. So, he'd have to do the same thing again if I change my mind now. I don't think that will be a problem, but it certainly is a pain. I suppose it's worth it to get the right fit.
