In the meantime, I would remind the people who would like to experience a vintage keyboard to take a look at the Unicomp model M keyboards. They are not Model Fs or beam spring, but are rock solid, reliable, and sensibly priced considering their quality.
I've been twice the past year to buy their keyboards in-person in Lexington Kentucky US. They treated me very well. I can say this much, the full-size keyboard has a slightly nicer feel to it than the 10-key-less version, the key travel that is.

I’d get one if the shipping to EU would be more reasonable.
My Endura Pro started having issues three months in after arriving to me in 2013; I remember how it was $99 and shipping was $98, and then I had to pay VAT on it.
It died quite quickly after and become parts donor for old IBM Model Ms I bought out from people’s attics. It was a wonderfully repair-unfriendly thing, too.

Has their finishing improved at all? A coworker bought one, maybe 15 years ago. He has to spend time with a file to remove all the remnants of the molding process. I'd expect a nearly $200 keyboard to feel finished and not have sharp pieces poking out all over the place.
I've long thought about getting a Unicomp, but seeing how poorly finished they were always gave me pause and made me question what other shortcuts they took.
