I bought one too, even though the black is my least favorite Cherry switch. Maybe I will find 21 greens or clears sometime.
I had a couple of outboard numpads but I sold one and now the Enter is not working on the other (rubber dome).
None of this will be necessary until someday when I give up my aircraft-carrier-sized boards!
edit - Arrived today, very nice, but caps are a bit lame. Pad printing is wearing off the Enter.
