Game show buzzer

I am fairly new to electronics and this site and have searched this site a million times and cant find what I'm looking for. I need a game show buzzer that runs on a 9 volt batery and a lock-out system. It would be nice if it was an 8 buzzer system with an LCD screen that displayed the buzzer number. I would also like an aproximate cost for it.

Thanks
