Be sure to check out the Speed 4. At $6500 list you basically get a naked TT600. Tuned for more mid-range than the TT or Daytona, so it should be more forgiving around town. Personally, I think it looks pretty damn good in black. Probably cheaper insurance as well.
There are lots of 600cc class starter bikes out there now, but the recent mag reviews put the Speed4 head and shoulders about them (Honda 599, Yam FZ6, Suz SV650).
