I know Ducky keyboards are highly ranked in the mechanical world too.

I've been really into the idea of building my own mech keyboard, but digging more into it and doing more research, it's way more expensive than to just buy a premade one. Buying a premade keyboard for $75, sure, but a 60% PCB by itself can cost more than that. Then getting into full sized PCBs and custom ones with media keys/macros, those are so much more expensive. Building one could be 3x more than an assembled one.
DasKeyboard looks awesome! Really great concept but it looks like a lot of micro managing.
Loved my Corsair K70 (https://www.corsair.com/us/en/Categories/Products/Gaming-Keyboards/CORSAIR-Gaming-K70-Mechanical-Gaming-Keyboard-%E2%80%94-Blue-LED-%E2%80%94-CHERRY%C2%AE-MX-Red/p/CH-9000085-NA)
But since its down due to neglect, I've been on this Logitech K840 (https://www.logitech.com/en-us/products/keyboards/k840-mechanical-corded-romer-g.920-008350.html) for some time, picked it up on sale for $60 and cant complain
