OK, was there and took one Keyboard with me.
The Chicony KB-5152 has blue ALPS (bottom in the picture). So far I like them very much. Could become my new favourite. Quite Model-M-Style, not that stiff and actuate a bit earlier. Compared to white (old) ALPS much better in my opinion (Much lighter). Normally I use MX Blacks.
The Phillips is not on the picture, was a Model-M style rubberdome.
I left the Cherry at the seller as I didn't like the Switchet at all - worse than standard rubberdomes in my opinion.
One was very strange (I think it was the keyboard at the top): I was definately a rubberdome, but when you press the button it was like it folded from the top to the bottom (meaning there's some sort of bracket at the top). Very strange but I didn't take it either because it was a rubberdome and way too expensive.
So in conclusion: one great keyboard!
Pictures will follow in the according thread. I'll post a link here.
PS: the # Key on the Top is rather irritating. Good, that German language doesn't use an appostroph very often.
