For $7.5K you could get a new bike OTD from one of several dealerships selling close out 06 models.

Check ebay. I know I've seen the 06 GSXR 600 for $7.5K new eBay Motors: Suzuki : GSX-R (item 130062978256 end time Jan-06-07 08:25:54 PST).

I think I've even seen them for less, but can't remember exactly.
