Used is a great suggestion. I'd think about your timeframe for being on your new bike and consider building one up. It would help if you had some experience with bikes or know someone that could help with the fine tunning. But you can certainly stretch you dollars further if you buy a piece here and there on sale or ebay. I built a bike on the base Allez frameset with 105 black and Ritchey parts for $635. Your biggest 3 expeses will be the frame, the wheels, and your shifters. But getting Keo pedals from probikekit for $34 to the door, helps stretch your budget. It really helps to know someone that has some shop experience that can help and offer advice. Good luck, and let us know what you do.
