I would not pay more then $4k for either. Not sure where you live, but in Florida you should be able to find a 2003 or 2004 with no more then 10k miles for 5 grand, no damage. Checked some local bikes for sale, did not find an GSXR 750's at this time, but a 2005 GSXR 1k just sold for $5500 w/ 7900 miles.
