Matias has a bunch of different layouts. I'm using this one, personally. Only complaint is the build quality for the price; the plastic on it feels really cheap.
The switches, however, are some of my favorites, especially as far as Tactiles goes. I have some Zilents v2 on the way, and I'll happily drop a comparison when they arrive, but the force curve on the Matias Quiet Click is very, very enjoyable. It's almost like a double tactile event...
