User blog:Waterworkz/Rarest Gorillaz item?

I own a lot of Gorillaz stuff, including (BUT NOT LIMITED TO), D-Sides Deluxe set, (Two) Demon Days Deluxe set, Rhinestone Eyes Promo, Clint Eastwood Radio Vinyl, Clint Eastwood Green promo, TCT/Clint Eastwood VHS set, Spacemonkeyz Taiwan Deluxe set, Spacemonkeyz promo, and a LOT more. But what's the rarest CD item there is?
