This is a great deal if you owned the old one and already have the buzzers. I posted a deal like this before, i think from play, but for singstar and recieved alot of heat and rep. Hopelfully the same happens with this one. So yeah the only downfall is the fact that there isn't any buzzers included but somebody may have some for sale here on HUKD so good luck and please leave rep. Also if you do a search for Buzz on shopto.net there is another Buzz game - Buzz! Brain Of The UK (Solus) - for £19.99.
By the way the PS2 buzzers are compatible with the PS3 :)
