Where can I buy a good web cam?

[Michael-XE]

I'm trying to buy a good web cam for my PC. I just bought on from Walgreens for $25. It was made by Logitech. The picture was terrible (as in you couldn't see anyone in the pics), so I took it back. Where can I buy a good one and what price am I going to have to let shell out for it? If you have a ny suggestions, links or whatever please fell free to post them...thanks.

Nothing too fancy, and you can get it at any computer retail store. I have been using it for a few years, been good to me.
