Which is the best Webcam that gives a clear picture with maximum size?

Here are three webcams which give us batter quality and clear picture. Try one of them it will fulfill your conditions I think so.

First one is Phillips SPC 900 NC with best quality picture on a dedicated webcam. Best Quality and good face tracking software. Well worth the money.

Another is Logitech Quick cam Pro 500 with nice crisp clear picture from its wide angle lens. Very small and neat. Fits notebook PC's easily and comes with a carry case/pouch. Very good value for money with this little gem.

Last one is MSI Star cam: - Although classed as an entry level webcam, this unit provides excellent Performance.
