scrap the 1000cc biked from your list (dangerous, no need for 1000, and more $$$ than the 600-750cc bikes that are ALL you need).

Add the GSX-R 600-750 to your list. One of the best sport bikes out there next to the 600rr.

I for one would remove the Kawi just because in reviews the Kawi's are always last.

There are a couple 600rr's around me for $5k, a few (older model) GSX-R's for $5k, and 2 675's ($6k)
