It costs too much to send them between many European countries also, I think.
One thing that I did the other day was to look up a local "hacker space", where geeks hang out. There are hacker spaces in some places that are oriented towards machining things out of wood and metal, and that is what I was looking for. However, this one was oriented more towards computer geeks, electronics geeks, anime fans and geeks who play various types of games (role play, board games, card games, etc..)
There was lots of vintage computer equipment there, up and running, and stacks upon stacks of old Amigas in the bookshelf. I was told that they used to have a whole lot more, but they had to move a lot to the dump because they ran out of space ...
I got to try my hands on a tactile - but not clicky - Dell 101W, a few granite SGI boards, a linear terminal (?) board by Keytronic that I had never seen before, a linear Amstrad 128K, a Sun Type 5 (rubber dome, but is otherwise the most beaauutiful keyboard in the world, if this one just wasn't so dirty) and a Sun Type 6 (rubber dome). There was a lucky b****rd there who had just found a nice Cherry G80-3000HAD (ISO layout, Cherry black, double-shot keys) in a dumpster and was replacing the coord. Unfortunately (for me), it worked flawlessly once repaired, so I did not manage to convince the owner to sell it to me ... Unfortunately, I had forgotten to bring my camera.
That is my advice if you want to try out various keyboards: look up hacker spaces.
