Well, after an hour or so typing on this keyboard, I must say that I'm absolutely in love! I've never used a mechanical keyboard before, so my opinion might not be worth that much (or to people who are considering switching over, maybe this is useful advice).
I really recommend this board. I'm still getting used to not bottoming out the keys, and I'm already actually doing really well in that regard. I'm a little bit scared that I"ll never be able to go back to a membrane keyboard now...
Regarding comments on the build quality of this board, I have to say that it seems extremely solid, especially for a $50 board. It's plenty heavy, but not too heavy. I'm considering taking this thing to work with me.
I've also seen comments that the switches are higher pitch than other blues on, say, the Das III. That might be true, but my comment would be that I really like the clicky sound that this board makes. It does not annoy me in the slightest. But, again I don't have much of a basis for comparison.
As an aside, mine has no logo on the top of the board whatsoever, which I actually really like. Now, if only I can dye the keys...
Anyway, my conclusion is that this is truly a wonderful keyboard, and I highly recommend it to anyone who just wants to try out a better typing experience. I'm sure that by spending a lot more money, and trying out a lot of other keyboards, a better board can be found, though.
