Best Webcam?

I need to get one as a present for someone - what's the best one?

some of the logitech ones are very flashy, with face tracking etc.
the quickcam sphere is a lovely cam, which, if i could afford, would get:)

Got one for my daughter, superb.

I can't believe how much the price varies...

My dad got a Logitech Quickcam 4000 SX or something like that, very nice cam, extremely clear image even in very low light conditions, face tracking, built in mic, reasonable price, and the usual suspects.

- Logitech QuickCam Communicate STX ~ £35.78

- Logitech Quickcam Pro 5000 ~ £36.30

- Logitech Quickcam Fusion ~ £47.93

All good, I'm gonna be getting the Pro 5000 next time I'm up at Scan HQ - check this out for photo and video examples.

EDIT: The Creative Live! Cam Optia ~ £32.04 + £7 cashback, looks pretty good (see here)... although it has no mic.
