SlagathorThis keyboard is standard, it will work with almost all of the keysets on the market. As long as your keyset is MX compatible, and doesn't specify it was made for Corsair, Razer, or Logitech.
SlagathorThe one thing I had to learn was the the WASD row markers are inverted from where most caps just keep that in mind when checking.
The ESC/F row is marked as R4 in WASD, most capsets call that R1.

But yea, $120-$150 for caps is what I gather when researching. Ooof (I'm holding out for Oblivion SA with Hagoromo Alphas)
