Third Party AC Adapter for G4 iBook?

I see that there are 3rd party replacement units for the iBook AC power adapter - does anyone have experience with them? Is one better than others? Should I just pay $80 for the Apple model?

Are any of the 3rd party models WHITE?

I've seen those, and I like FastMac, but it looks like they might now have them for the G4 iBook, becuase that link on their site is disabled.

DOH - thanks.

Have you used these? Do they have the little orange/green ring to indicate full charge, or is that an APPLE exclusive thing?
