Which webcam should I get?

I would like to purchase a webcam, mostly for video chatting with friends and family, but I'm kind of confused about which ones to buy...

I really want a nice one that will clip onto my laptop, comes with the usb hookups, good video quality and such.

Also I want the software to edit photos and has all the video effects. Like the ones that distort the pictures and such.

I would also like to keep it pretty cheap. between 20 and 25 please :]

Please let me know soon! I really want to order this thing.

Thanks!
