I have to jump in to recommend the keyboard I use and like so much. It's a little different from what you were looking for but it's perfect for me and I hope to others.

It's from
A4Tech and is sold as part of a wireless Kb&Mouse set. I love A4Tech wireless mice. Although the KB uses rechargeable AA batteries I only change these about two times a year and the wireless signal receiver doubles as a battery charger. Same for the mouse signal receiver. The reason I prefer wireless is because I have a big desk and the KB and mouse routinely are on top of large paper drawings sheets that I work with.
The keypad on my KB gets at least as much use as the letter keys and here is the real reason for this model preference: the
keypad is on the left!. I find this is a more natural location for use with the left hand and allows for continuous right hand use of the mouse.
I seldom have to type long times and am not the most accomplished typist but I use all fingers and I prefer this A-shaped key layout to the traditional one. I like how the keys travel and fell firm. The detachable wrist pad adds comfort.
I use most of the multimedia buttons but have still to configure all of these for use with my players and other non Microsoft sw. There's also a mouse wheel on the KB that doesn't get used at all.
