I am having so much trouble finding a good bike in my price range. I really don't want to spend more than $5,000 but if the deal is right I can go as high as $6,500 out the door. My choices are (in order):

1. Honda CBR600
2. Kawasaki Ninja 600
3. Yamaha R6
4. Honda CBR1000
5. Triumph Daytona 675
6. Yamaha R1

My ideal bike would be a 2007 or newer CBR but I don't think that is going to happen in this price range. What year bike do you guys think I can get in this price range?

EDIT: Under $5k is acceptable too.
