My flat mate just graduated.
He just built a new gaming machine with a big LCD. The only thing he's missing is a nice keyboard, the one he's using is a beater.

I'm looking at:
Das keyboard,
The Saitek pz30au
and the Sidewinder, though I'm leaning against this one 'cause he's a Linux user.

I'm pretty sure all of these have N key rollover. Otherwise I have nothing to look for. Something solid that will last for a long time.

Any users of the above keyboards that can weigh in and tell me how great they are?
TIA

I have the Das Keyboard Ultimate and it's a nice keyboard but the darn space bar squeaks sometimes. I had to send my first board back because of a crack in the casing.

Both the orriginal and replacement boards have pretty loud spacebars. It's a decent keyboard.

I have a Deck 82 fire keyboard which I love. The keys feel great to type on and it works great for gaming. I love the small form factor and the LED lights are a nice touch as well.

So far, I would reccomend the Deck over the Das keyboard from my experience. I've had my boards since about January this year.
