I've just bought and got all possible keys from WASD Keyboards Individual Textured Cherry MX Keycap here: http://www.olivierpons.fr/ergodox/7-ergodox-wasd-keyboard-customisation/ From what I can say i'm satisfied but you just cant differentiate easily between each key and as you can see in my picture even though it's French you'll see they're not the same height as the Ergodox. This is very useful if you need to really differenciate. The only problem is that they're not soft, they're a bit harsh and it's less pleasure when typing than "totally flat" keys. That's why I've voted for the Custom Art keys first.
