Rarest Video Game Consoles

I haven't posted here in a long time so excuse me if this is in the wrong section of the forum. Anyways, what are some of the rarest video game consoles ever made? Atari Jaguar is one, Sega Master II is another, what are some other ones that are pretty hard to find?

The nomad and the Amiga 32 spring to mind

the intellivision.

Bentley Compuvision. I had one that was still running right up until I got rid of it about 3 or 4 years ago:

Please say Gamegear is worth millions...please say gamegear is worth millions....Morphic

Dont worry, it is worth millions of dollars...if we're using Zimbabawe dollars that is.

Anyway, people in this topic seem to be confusing "old" with "rare". Commodore 64, Sega Master System, Virtual Boy, etc. are not rare consoles. They may be a bit uncommon but they're hardly rare. A rare console would be something like the Neo-Geo AES or CD, though truly rare consoles would be the abysmal failures that you've probably never even heard of before and no one cares about.
