We haven't asked about your budget ... another option are the cross bikes built by Rodriguez at http://www.rodcycle.com/ Although not women specific, they offer 15 different sizes which is much broader than most builders. The Rodriquez starts at $2699, the Terry at $2950, and the custom bikes more. The Surly, Soma and others will be less. If you are on a budget, shop for used bikes (there's a lot of juniors locally who outgrow their bikes).

I agree with Uforgot & bboston 88 about paying close attention to the measurements. And try to test ride. Last week I let a woman who rides a Q'Roo TT bike similar to mine ride my cross check bike for a comparison. She came back with a huge grin! The cross world is pretty friendly and wants to recruit new riders.
