Trek
I had a Trek 7000 small frame and it seemed so big to me and I'm 5'4". I really didn't like the ride, the components they seemed cheesy to me.
Have you looked at Specialized? They make a really small frame for women or at least they did 4 years ago when I was looking. I know a couple of women who got Specialized bikes and really liked the fit.
Best way to decide is to test ride everything you can. Happy hunting!

"The bicycle is just as good company as most husbands and, when it gets old and shabby, a woman can dispose of it and get a new one without shocking the entire community." — Ann Strong, Minneapolis Tribune, 1895
