[G4] Webcams

[Chaim The Squirrel Keeper]

I recently sent my sister a Quicksilver with Leopard.  When I talked
to her on the phone to see how things were going with it, she
mentioned that she'd bought a webcam for it, but she didn't think it
was compatible with the QS and she was planning to return it.  Can you
guys recommend a good webcam to use with a G4?  I'd probably get
myself one, too, because she thought it would be nice to video-chat
with family.

Oh, and speaking of chatting, what are some good headsets to use with
Skype?  Or maybe just a good microphone to use with my existing
headphones?
