Webcam

Can anybody recommend a decent webcam for a macbook that is easily set up, available at a retail store and is not over $60?
I know this might be asking a lot, but I need to pick one up quickly as the person is leaving for overseas on Monday.

Thanks for your help.

Doesn't the macbook have an iSight? Anyway, using macam (http://webcam-osx.sourceforge.net/cameras/index.php) the mac can use a lot of standard cameras, there's a list in the link. If you install macam and then plug in the webcam into the USB port it should then work in any program such as Photo booth or iChat. I use it on my imac G3 with EvoCam and a logitech quickcam to broadcast.

Thanks for your reply.
It is an older macbook.

Didn't all versions of the macbook have an isight ?

Or are you using an iBook and have called it a Macbook by mistake.
