I'm looking to buy a webcam to use with Skype - my only requirements are that it handles low light conditions well and has a reasonable image and build quality. While I would go for an iSight, it's really just too expensive (even now). My budget is around £20. Does anyone know if my 1.67 GHz PB G4 would be able to handle the 720p feed from a camera? QuickTime just about manages to decode 720p videos, so I'm a little worried about how it will handle the webcam. Any comments would be appreciated - thanks.
