Or, you can ask questions about keycaps in the keycaps subforum and get an answer there *gasp* !
Ripster would you please tell me what is the reason people want these keys? What keyboards do people want them for?
Anyway, People seem to like doubleshots. They are always ABS plastic, but the legends are shot "through" the keycap and won't fade until you've worn through the entire keycap. I have a set of used cherry doubleshots, and they look really nice, with the white lettering on black keys. The legends look really sharp.
Personally, I prefer PBT, but the cherry doubleshots are very nice. It's really the only thing I use that's not Dyesublimated PBT. The legends are a little "blurrier" on the PBT dyesubs.

The alphanumeric keys should work on any cherry MX-compatible(filco majestouch, leopold, CMstorm QF rapid, Poker, etc.) keyboard, but you often need to get other keys for capslock, control, alt, windows, menu, spacebar, and sometimes shift. These are usually made as "moogle" kits. Check the GB forum for some good ones.
