I have a Unicomp (which is based on the IBM Model M) Sun Unix Spacesaver USB keyboard: https://www.pckeyboard.com/page/product/40PSA https://www.pckeyboard.com/page/product/40PSA It's great, and what's not to love if you're a POSIX guy? The Ctrl and Caps Lock keys are swapped, so the Ctrl key is on the home row like God intended. It has buckling spring, positive keyclick action and it's so good if you do a lot of keyboard input or use Vim and/or Emacs. The bottom plate is steel and it's heavy, it won't slide around on my desk. Sure, for custom mechanical keyboard snobs, the keycaps aren't anything to write home about because sometimes the key characters aren't properly centered on the key surface. But my keycaps look OK, maybe I just happened to get a good one. And it doesn't bother me anyway because I never look at the keys when typing.
