I am looking for a good webcam. I know a bunch act as "digital cameras" too, but I already have a Canon A70 so I don't need that feature. Does anyone have any experiences and can comment. Basically, I just want something that gives a nice and clear picture over MSN and is good in most light situations (I heard that is a problem). I loooked at the LOGITECH QUICKCAM PRO 4000 and ClickSmart 820.
