@Halvar: That purple set with esc, F5 to F8, Arrows etc... man I would go for it!

Would look soo great with the beige caps
@Jmneuv: Good advice with the ebay Kleinanzeigen, I will take a Look
This Weekend I will try to modify the caps and I will post the results here...
I got 2 Sets of doubleshot Keycaps from g81 Winkeyless boards and I never thought it will become such a pain to get the missing caps...
Thanks a lot for the good advices, I will keep an eye open for a set of lasered PBT Caps from a g80.
I ususally go for g81 when I am looking for keycaps because they go away for really low prices but this off center shit supprised me!
A friend of mine has a sandblaster, I will try to sand the ugly legends down from the stock Quickfire caps, this could turn out really nice!
