As far as I can see this is Microsoft's flagship webcam, I couldn't find it any cheaper than this anywhere (delivered).
Seems a good price for such a great spec webcam.
Make your own minds up tho!
Widescreen technology is everywhere these days, built into virtually every new notebook, desktop monitor and flat-panel TV, and today Microsoft Hardware sets a new standard for webcams with the launch of LifeCam Cinema, the first consumer webcam on the PC to offer widescreen video with a native 720p sensor. The timing couldn't be better, with more and more people going online to share videos with friends and family; in fact, more than 10 million videos are uploaded each month to Facebook alone. LifeCam Cinema webcam's 720p widescreen sensor will deliver clear, quality videos - without leaving anyone out of the shot.
