ZSA has a few variants that are worth looking. It takes a bit to adjust, be prepared to spend a week or two typing slow and needing a cheatsheet to know which layer contains which key/function.

There’s also a thriving market for custom built keyboards on Etsy. Corne and Sofle layouts are popular and if you’re feeling extra DIY you can just buy the boards/switches/controller/case individually and solder them together. The controllers are typically using QMK or ZMK firmware and there’s a whole sub-community of fellow nerds so you’ll find plenty of guides/git repos/configs to help you along.

I went with the ZSA keyboard first, they’ve done all of the hard work for you (and their layout creation tool is very nice). Now that I’m familiar with the ecosystem/community I’ll probably build my next one so I can make a custom sized/sculpted layout (gotta justify this 3D printer somehow…).
