Mad Catz Call of Duty Stealth Mouse (rebadged R.A.T. 5) - $24.99 FS
Dealfisher has the Mad Catz Call of Duty Black Ops Stealth Gaming Mouse for $24.99. I have never purchased anything from this vendor though so maybe someone can speak to their experience with this site.
This definitely appears to be a rebadged R.A.T. 5, which is currently selling for $69 on amazon.
