I've recently been looking to buy/reuse an old keyboard similar to IBM's model M, but it seems to be impossible where I live. And the computer stores I've visited here don't stock any (and some don't know what buckling spring keyboards are...).
Anyway, I stumbled upon something interesting today, Das Keyboard II:
http://www.daskeyboard.com/So besides the "clicky" design, it has no character labeling to increase typing speed (piano style!).
Pity about the pricing though, lol

but it seems to be made to last ones entire career...
