I love keyboards. Specifically I love remapping them with Karabiner to extend them to do more awesome things for me.
I am currently using builtin 2018 MacBook keyboard and love it. I love the low key travel as I get tired typing on most mechanical keyboards. The only thing I would change from that keyboard would be split space key into two keys for more remapping awesomeness.
Gateron Browns low key travel mech switches maybe are nice. Need something low key travel ala macbook.
Preonic - Beautiful keyboard.
Preonic Light - IMO better than Preonic. Would be even nicer with Kailh switches & it being wireless.
Dactyl Keyboard - Parameterized ergonomic keyboard.
Redox - Ergonomic split mechanical keyboard.
Helix - Compact split ortholinear keyboard.
Kailh Low Profile Keycaps - Blank - Low key & awesome.
Cookes and cream Ergodox - Neat setup.
