I'd also suggest a GSX-R750. Either '06 or '07. They have the same frame as the 600, just with a bigger motor. In my opinion, it's pretty difficult to get all the potential out of a liter bike on the streets. It's more than most people need. Plus, with the 750, you'll get cheaper insurance rates. I had an '06 600, and it was a really fun bike. Cornered like nobody's buisness and was plenty fast for me.
