I was going to suggest the group buy at deskthority, as well. What, exactly, do you need? I have bags of incomplete sets, and I was going to be ordering another set to replace the incomplete set on a keyboard that I recently received that are stained beyond cleaning, so odds are good I have what you need.
You pay shipping, and they are yours, if I have them. I even have ISO enters and left shifts, as well as the stabilizer plug you would need for the vertical keys.
