The problem is I'm having finger pain from typing, and need a solution quickly. I have lighter springs on order, and just want a keyboard I can pop them into. I can solder, and eventually I'll make a custom keyboard, but right now I just need something to type on! So I guess I need to update my requirements:
60%, 75%, and 87 key are all fine.
Disregard PBT requirement
Just need something without a number pad that will let me swap springs immediately.
