Yep, I would just get the 50cm Kilo TT, it's a great bike for the price. Or, the 49cm Windsor (same thing as Fuji Track but cheaper, components/frame are the same). Both from bikesdirect.com. Lots of people on this forum have those bikes and love it. You can upgrade the parts later (when/if you break them) or if you start getting picky.

Btw, how tall are you? That can help too.
