Capture Card for Mac

Anyone know of capture cards that work on Macs. I'm looking at capture cards and need help figuring out which ones are for Macs. I'd appreciate the help.

 

What kind of Mac do you have, if it's a Mac Pro / Powermac then there's more to choose from..

 

Canapus Firewire

 

I have a G4 Ibook.

Works for Mac and Windows and allows for resolutions up to 720p with component

 

That seems a bit pricey. I'll keep it in mind though. Thanks. Any opinions on this:
