I was looking at the sk-7100's to get a "real" keyboard with working alt and function keys for the GCT since I use Linux and not windows.
Anyway, all of the 7100's that are out there now are selling for $47+.
However, on pricewatch.com there are a bunch of Siltek sk-7200 IR keyboards selling for only $15. I just ordered two, and will update here to confirm that they work (they should).
They are, unfortnuately, beiege.
