one thing to keep in mind with the goldtouch (filco numpads too) is that they come with 0 and 00 keys instead of a 2x 0 key. if you care about keycaps you're gonna want to replace the keycaps on the goldtouch right away, and tracking down the right 0 and 00 keys is not as easy as finding a 2x 0 key.
Tsangan's CCnG kit came with the right sizes, and there are black cherry doubleshots that came with those too.
