I've been eyeing the Ergodox-EZ for a few months and this was an instant buy for me. Lately I've been rotating between TKL keyboards and the Microsoft Sculpt Ergonomic, but my right wrist is still getting worse.
I looked at over a dozen split keyboard options. Seems like no matter if you build or buy, it'll cost around $300. I decided I didn't want to also buy a soldering kit and wait months for parts to arrive.
Here's a comparison site between all the known split keyboard layouts (no moonlander yet though): https://jhelvy.shinyapps.io/splitkbcompare/
