I'm looking to purchase my first bike this year and I've looked around some, as well as read through all the New Riders threads on this site and Ive narrowed it down to these bikes:

Honda CBR600 F4i
Honda CBR600RR
Yamaha YZF-R6S
Yamaha YZF-R6
Suzuki GSX-R600

If anybody is selling a 99-00 or newer bike in any of these models, or if you know of anybody selling one, please let me know. I dont mind buying a bike with a rebuilt title, as long as it is in good running condition. My budget is about $5000. Thanks for any help and advice in advance guys.
