I thought they were too much when I was in grad school in the 90s and you could find them on ebay for $500.... $500 for a goddamned fan! Well, it's not like they made more of them since then, and many have been parted out or thrown away.

Those pancake fans are really cool!

Oh, no argument that they look cool. I was just expecting the price to be a lot lower!

Does anyone make good-looking modern reproductions?

Nope. But for $20k you could probably pay a skilled machinist to make you a couple of them.
