Gentolman, one more thing. Pay attention to the tires on anything you buy. If you are going to be on pavement, the fatter and nobbier the tires are the harder you will work pedaling. The flip side is the really skinny tires that you see on some road bikes are susceptible to pinch flats when you hit a pothole or some such. So not too fat or nobby, and not skinny skinny either. The mountain bike type tires are better suited for off-road riding, going over rocks, roots and technical off-road riding.
