From a quick look that is about 500€? (100 for the capture and about 400 for the cam on ebay). Also, you probably still want a stand, battery, lighting, microphone... That is at least 5 times as expensive as a webcam. Is it at least 5 times as good? If you already have a system camera, that might be a good alternative, but otherwise?
