HELP!!!!

I need a power supply for a mac powerbook g4... like right now.

anyone have one I can borrow until I can buy one? or where can I buy one?  remember, I inherited this mac, and still no nothing about them...

EDIT: The mac store in the North Shore Mall (pebody, MA) had the thing. Yes, I just got back from *another* 1.5 hours in the car today.... But I have a computer again.
