I just bought the Das Keyboard from NCIX this week and so far I love it...
Metadot Das Keyboard Ultimate Model S Mechanical Keyboard - Metadot - DASK3ULTMS1 (8 55800 00117 3)
All of the reviews that I have read about it also say its one of the best on the market. It is very solid, clean looking and best of all the sound that the key's make is like music to my ears.
When I was looking for a gaming/typing keyboard I wanted something that didnt have all the bells and whistels of a typical gaming keyboard... I.E. back lighting, additional buttons, LCD screens etc. I wanted something simple that looked great on my desk but also performed at a high level.
So far I have found this to be the case with the Das Keyboard... Highly recommend it.
