I'm looking to get a decent webcam for my Powerbook G4. I have 1.33ghz with 1GB RAM. Currently I'm using my miniDV camcorder with a firewire cable, but it's sort of a pain to setup and adjust everytime. Do you have any suggestions as to which webcam I should purchase? There seem to be so many options out there. Would the quality be the same or better than my camcorder setup right now? Is it best to splurge and spend the money on an iSight or do you think there's a better value one out there? Thanks.
