Random rec needed: Favorite computer keyboard.

I have to type a lot for work and I want to get a comfortable keyboard that I can type quicker on, if such a thing exists. Any recs?

I just bought a wireless (solar/light bulb powered) Logitech one from Amazon. It's nice and flat and comfortable and doesn't aggravate my carpal tunnel.
