How can I run a game show in a college class?

I want to have a game show type test review. Something like Jeopardy, but it wouldn't have to be exactly. I'd need something for buzzers (not too expensive) and a way to present the questions or clues. Has anybody done this in class, and how did it work?



(By the way, the Jeopardy classroom set is over $500 and on back order, so not an option for me.)How can I run a game show in a college class?
use powerpoint for the questions and bicycle horns or bells for the buzzers
