I'm 5'0" and about the only bikes that fit me are Trek and Specialized. I prefer the Trek. I actually have a Trek 2000 47cm men's bike right now and will be looking the 47cm Madones when I'm ready to upgrade. My current bike has the 650 tires and I do not want those on my new bike, which is why I'm going with the 47cm and won't consider the 43cm bikes for Trek. Specialized 44cm bikes are similar to the Trek 47cms. I would suggest also checking the 47cm and see what you think of those as well. Now there are some such as Giant and Cannondale that are just too big even in their smallest frames for me. I'm also pretty sure that I can looked up Felt at one point and just looking at the specs their bikes are too big.
Check out the Specialized Dolce as well as the Trek Lexa. Good luck in your search.
