i'm looking to buy a pair of webcams to video chat between iChat AV and PC AIM client. i'm not looking for the best resolution or picture quality. i simply wish to add images to IMing a distant friend. if this topic has been covered, i'd appreciate a pointer to those threads. i searched under "ichat" and "ichat av" and found nothing useful. first question: PC in question only has usb1. is that quick enough? i'd like to avoid paying too much, so if i can help it, i'd like to avoid spending $130 for iSight. what are some other webcams that work with Macs? i realize i need a FW webcam or pay for a patch... which is the better solution? for the PC, i'm pretty set on logitech quickcam zoom. it's $45, which is a good price for my budget. anyone with some experience? thanks for any replies.
