Is there a place where I can find Wireless Computer Speakers?

I Am having a Cook-Out next weekend and was looking for some wireless speakers to stream music from. Where is a good source that I should look?
edit: Please, I have a low budget and can’t get anything OVER 10 bucks. I don’t care what quality but I can’t spend LOTS of money.

When you say “stream music”, I am assuming that you mean from your computer system.

EDIT: OK, here is a good one. Transmits 100ft. Under $100 – Use your own speakers.
