text: video chat? i know almost nothing about video chat and need help.  i'll be needing to get webcams and figure out which service to use.  i'm looking for input on what combos work well for people (msn and logitech model x, for example).  don't want to spend more than $100 on the webcam and have realistic expectations...  thanks very much in advance- i got mine for 45$ but that was a long time ago so i'm sure you can get it cheap your best bet is a super walmart or target
