Anyone know of a source for replacement power supplies - besides Ebay?

I currently am in need of the following (some multiple units):

Sega Genesis
Sega Master System
Sega Saturn
Sega Dreamcast
Super Nintendo
Commodore 64
Colecovision
T/I 99-4a
TurboGrafx-16
Atari Jaguar
Atari XE
Atari 2600 Jr
Magnavox Odyssey 2
Magnavox Odyssey 2000/5000, etc.
Misc. pong / old school machines

I got all this as a lot, and none of them had power supplies...

Thanks!
