I am a new rider and looking to purchase a 2006 GSXR 600 or a 2006 Ninja 650. To the experienced riders, what do you suggest for me to buy?

If you are selling one of the above, I am willing to pay $4,000 for less than 25,000 km for either of the bike above. Of course the condition must be excellent. I may be far off the pricing but that's what I see in a lot of the for sale bikes. Again, I am new so any help will certainly be appreciated.
