Only if you keep getting new ones though and doing it DIY is pretty good too. Don't think I'd buy another keyboard again after building my current DIY one. Instead I'll just be designing my own from what I've learned that I've liked with this current one.
I had one of the ZSA moonlander split keyboards for a while and I loved parts of it. My RSI vanished.
1 - it was hard for me to use other keyboards that weren't colemak
2 - in split, if I took my hand off to use the mouse I found it hard to find the home row again. It took me like 2 months to learn colemak but never clued into the home row the same way I can on a normal keyboard.
3 - I felt like it took up a lot of space, not good for small spaces.
Uh oh I'm getting that keyboard itch again. I think my max qwerty was higher my normal was fine, like 100-110 is my comfort zone. Colemak was so fluid, and I do still get RSI if I type a lot of my non-custom layout qwerty...
