Just to add another keyboard to the list, the KBT Pure is a Cherry MX version of the HHKB2 layout, and available for around $100. It's well built, compact and you can reach all keys without moving your hands too much. Good key feedback, and I can type "pianissimo" when I pay attention to the MX Brown's click feel. I haven't gotten any faster, as 80% of my typing is still on a Thinkpad keyboard. Also the Cherry keys feel much too high and don't have a trackpoint.
