I built a crkbd using a PCB I bought from littlekeyboards.
I was a happy HHKB 2 Pro Type S user for many years, but since switching to the crkbd I have no intention of ever using the HHKB again.
It required minimal soldering (the ProMicro and OLED hotswap sockets). I went through a few sets of switches before I found what I liked, took a few months to find a combination of layers/layouts that worked for me, and had to learn how to use an ortho keyboard in the process, but it was all worth it. (I’m a Dvorak+QWERTY user, and think the switch to ortho was was easier than learning Dvorak, and has a similar feels good motivation to continue learning it.)
I never had RSI problems, but what I did notice was with the split keyboard and tented cases, my posture opened up dramatically. My shoulders no longer have an anterior tilt when I type.
