+1 for the Quickfire TK if you want to keep the numpad and reduce space (also known as 90% keyboards).
I use one at home, and with AutoHotKey have it setup so that I don't switch between the numpad on/off modes. Instead I hold control as a modifier for arrow keys and other functions. Works pretty well, but do note that the bottom row is not standard layout. Specifically the spacebar is almost impossible to find decent replacement keycaps for. I've just got a new keyset in and have had to leave the original black spacebar in.
Other notable keyboards in this area are the Cherry 1800, Plum 96 and then it's going into the customs market.
