As others have implied, that part is a deal-killer for the online route. You might not even come out ahead on the initial outlay when paying shop labor for setup, not even including future tune-ups.

Between the two bikes, the Nashbar flat bar is spec'ed better in my opinion although I question the "road bike" designation. It would be a fine bike for your commute, especially at that price, but only if you're willing to do the setup and maintenance. It's fortunately not that hard if you decide to go that route.
