Decided my keyboard needed cleaning so I went ahead and bought some keycaps for it while I was at it.
It cost me 300$ when I bought it since it is a custom made keyboard with all cherry mx green switches (you rarely find all keys in green). I personally love it and even more so with the new key caps.
@sojournTime I much prefer clicky, the louder the better. That said green are supposed to be louder than blue but they are about the same, maybe a bit quieter.
