i currently use a labtec usb cam for ichat (using ichatusbcam) and planning for a firewire cam. my budget is barely large enough to get an isight so price is not a great factor... i've taken a good look around at firewire cams, but i don't know how well they compare... I currently have my labtec cam on a little stand where it is over my laptop screen, so something like an ibot would be ok. so what should i get? an iSight? an iBot? or something else? what say you?
