Source for cheap buzzers for electronic circuit lesson at school?

I am looking for about 10-15 buzzers for an electronic logic board lesson for my grade 9 kids. Does anyone know of an inexpensive source for these? Thanks

Ebay, search buzzer in business & industrial

Try this one on for size.

Since you didn't specify anything about the electrical characteristics you need for the buzzer, I can only guess about what you want. If this one doesn't work for you, then come back with a follow-up post and let us know. Maybe one of these will be more suitable..

Thanks for that, I am also trying to find larger lots - like 20. I hope the ones I have seen are the right ones for the project:

I just want a noise like when someone gets an answer wrong in a game show, when student pick the wrong answer.
