I’m going to against the grain a bit. If you liked and want the oldschool Thinkpad feel, look into getting a Topre board. Check out Leopold or Niz, both are decent topre clone brands.

Also, if you live in a metro area check and see if there’s a mechanical board gathering, possibly giving you a broader flavor of what’s out there that might fit your taste.

For switches:

Durock Shrimp or Gazzew U4 switches for slightly on the premium side. If you feel .65 per switch is a bit much, I highly recommend Haimu Whisper (.30 cents per) or Wuque WS silents - not as thocky as Shrimp or U4 but more comfortable to type on, imo.
