After upgrading my lappy to Vista I found my old webcam didn't work so I decided on this to replace it. I was very impressed with the quality - compared to my older webcam the image is sharper, and is further back meaning you don't have to sit far away from your pc to get in the picture!
As this is the standard model, it comes with "Fun Effects" which gives you a range of funky effects like 50's style video, fish-eye, neon, negative, etc, which can be implemented in MSN Live Messenger.
If you want extras such as Logitech® Video Effects such as adding objects into your live video such as hats,eyes, moutaches etc then you will want a deluxe version webcam as this supports it.
All in all, buying from Play Trade I got the best price I could find, it sits easily on my laptop screen as well as my LCD monitor for my desktop PC, and the quality is superb.
If you get, or have, this webcam and aren't getting a decent frame rate, go into "advanced options" and uncheck Automatic Exposure, and drag it down a few steps. This will make your frame rate shoot up to as much as 30 fps if your processor is fast enough.
