So I finally broke down and bought a film scanner from a stupid specific online auction website, and it didn't come with any film holders.

How does someone go about finding or making film holders?
I contacted Epson and they said it isn't made any more, so they don't support it.
Betterscanning.com has ridiculous prices on holders beyond all comprehension. I could buy a lens for that price.

Does anyone have any extra, by any chance?
