Depending on the number of rows and columns you want there is quite a cottage industry of ergo keyboards. I think the main ergo flat keyboard (staggered columns) with 3 rows 6 columns are the Gergo / Kyria / Corne depending on the number and placement of thumb keys (they can be found assembled to order). For 3d / sculpted keyboards, this person is selling assembled to order Dactyl manuforms: https://dactyl.bigcartel.com/ https://dactyl.bigcartel.com/ A good reference for flat boards is https://jhelvy.shinyapps.io/splitkbcompare/ https://jhelvy.shinyapps.io/splitkbcompare/ via https://www.reddit.com/r/ErgoMechKeyboards/comments/f5h3d6/split_keyboard_layout_comparison_site/ https://www.reddit.com/r/ErgoMechKeyboards/comments/f5h3d6/s... Then for the sculpted keyboards, mostly the Dactyl/ Dactyl Manuform families there are a bunch of vendors. The cheapest one is in the first link. Otherwise one guy is currently selling some of his split on reddit's mechmarket.
