Why do people get custom keycaps like that for games? When it comes to games, my thoughts are "If you have to look at the keys, you're doing it wrong". Imagine playing quake or something and having to look down to find where the WASD keys are.
I wish Unicomp would still do black keys with white pad-printed lettering like they used to. Asked them yesterday and they only do dye-sublimated, meaning the closest I can get is gray.
No worries Wyatt. That CounterStrike set won't work on a model M anyway. You're safe. Finding anything for a complete or custom keys other than what Unicomp and ClickyKeyboards have to offer is next to impossible, unless someone actually produces what you want. Good luck with that.
(I believe it might cost you more than you have invested already, substantially more.)
Of course you can find yerself one of those them there M13 trackpoint things. (13H6705)
