I know mechanical keyboards are expensive, but is that really the only reason why more companies don't make more of them? So far, at least for the Mac, it seems to only be a draw between the Das Keyboard Model S ($133) and the Unicomp Spacesaver M ($94).
The Das Keyboard Model S seems to be the better of the two but I'm sort of drawn to the old-school look of the Unicomp keyboards (I grew up using these IBM Model M or similar keyboards -- thanks dad!). And when I compare it in price to the only other real keyboard alternative I have for the Mac -- this not-bad-but-not-great Apple Magic Keyboard -- I guess paying a few dollars more for a mechanical keyboard that I actually want isn't so bad.
PS: But really, can somebody bring the cost of these things down?
