High Five, bro...
And the HHKB, I was fortunate to have a bro who went for training in Japan and so I bought the white -grey printed and blanks from amazon.co.jp. I now have key caps to swap.
The RF though, has no such luck and I am hunting classifieds for key cap.
But hey, this is Brobot therapy thread .. so, I feel better than the Zombro was MX variants. I still have hope!
