Linksys Powersupples

These questions are about the power supplies for the Linksys wireless routes.


I can't seem to locate the power supplies for few of my WiFi routers:

WRT54G (v6)

WRT54G (v2)

WRT150 (v1.1)


(1) What are the specs for these power supplies?
(2) Where can I find few of these inexpensively?


Thank you so much to everyone that took the time to read my post! Your responses are greatly appreciated!
