Good starter bike would be a Kilo TT or a Fuji Track from a local dealer.

I got my Fuji Track on sale for $299 and it rides nice. I've slowly upgraded everything except for the frame and wheels over the last year or so. It's better/cheaper in the long run to just buy a frame and build it up, but if you have nothing to ride and aren't exactly sure what you like I think it's fine to buy a complete bike and work on it between rides. That's exactly what I've done, good learning experience. Now I'm looking to pick up a nice frame set and build it up exactly the way I want it from what I've learned riding and working on my Fuji.
