I may have one for you, though it will be a while before I know for sure. I know I have one that is the "wrong" color (terminal emulators use opposite color blocks for the F keys), and I know I have a Cmd 5 key, which is the old version of F5, in the correct color. I haven't fully sorted my spare keys yet though. Oh, and I have one that is dyed purple, as well.
Unless you want a wrong color or Cmd key, I would just take the offer from Ascaii. It will be quite some time before I can find it, if I even have it. Not sure how long you're willing to wait, but it will likely be a month or so before I have enough time.
