+1 again. There are a lot of manufacturers who make very similar bikes. I look for a shop where they spend as much time with the occasional rider as they do with the racer, and one of the first things they should talk about is proper fit. Ask how they do a fitting. It should be a bit involved: they should have tools for measuring you. "Stand over the frame" is not good enough.
Good luck! The fun part is test-riding to your heart's content.
