Most Logitech webcams are supported by Linux.
If you video chat a lot, or record a lot of videos sitting down at a desk, it is a good idea to buy a webcam.

The best webcam on the market is Logitech. It is has good video quality, is durable, and has allowed me to communicate with my relatives and friends for many years.

A Webcam is a camera based to be used on a computer, or laptop, some webcams (cameras) could be built on to your computer, if not then you can go to the store and buy a webcam, the webcam can be used for MSN, or skype, youtube, facebook, any programm that you can put a picture on if you want.
I would start by checking with local retail stores like Wal-Mart or Best Buy. Both offer great deals and variety on webcam related products.
Most webcams are terrible quality to start with (usually VGA). The only way to get round it is to buy a good webcam that has 3MP or higher. Once you've got a good webcam, you need a program to use it (try searching on Google). Skype allows you to do this as well from the 'settings' menu. It's quite straightforward, and you couldn't really go wrong.
Electronics stores like best buy.
