Thanks for your replies

I'll be definitely be picking up that Keytronics, for what's it worth it's not big money

What do you guys think about this one? It's a Siemens Nixdorf, I asked the guy to take a picture of the back, probably rubber domes, but maybe decent ones? Anyways I kinda like it for the collectible value due to the keycap shape

This one is a little more expensive (around 12-15) and it says MADE IN GERMANY, but maybe I can fight over that price

Definitely good as new, just some dust.
EDIT: found one nearly the same, but with windows keys and branding on the opposite side:
