good Powerbook G4 Adapter Replacement

The ol' G4 isn't the only Mac in the house, but I still love it for what I use it for.

Unfortunately, the adapter (pre-magsafe) no longer works. Have tried the Macally, but it doesn't seem to seat correctly sometimes, there's no glowing to indicate status, and I only know it's not seated properly if I keep my eye on the battery indicator on top of the screen.

Does anyone have any good recommendations?

Thanks!
