Either a Cannondale Women's Supersix Ultegra or the equivalent Specialized Amira. Or a 29er, or a mixte, though I'm leaning toward the road bike.
My first priority, though, is paying down my student loans. Sigh.
ETA: You won't regret the Charge. It's a tank, to be sure, but it's a comfy ride. It would be easier if I put the road tires I got for it on, but I'm lazy and I'll wait until spring to do that.
I should add that I'd like to pay a chunk of the debt down, but simultaneously save for the new bike. I'm viewing the new bike as an investment in my sanity, and to avoid the knee issues to which my current road bike has been contributing.
