1. I would recommend looking at reviews on the internet. Like www.download.com
2. Find one that is made to fit on a laptop. Creative makes one. The criteria for a good webcam is a resolution of 640x480, and the camera being made by a good company, like Creative or Logitech.
3. Buy a crypto notecam
4. Logitech quickcam for notebook PC
