Just a general comment but I've discussed with some people the fact that it seems like when you're under 5'9" (or under 175cm), you may find 26 inch more compatible with your size than 700c wheels. And I prefer the turning circle of 26 inch wheels.
I wouldn't put 26 inch wheels on a frame made for 700c wheels however. There's often sales of frames from places like Nashbar, Chainreactioncycles and Cambriabike etc.
