For a low-travel and ergonomic keyboard, check out the Microsoft Sculpt Ergonomic. It's wireless and has a standard layout which doesn't require any learning, including a real row of function-keys, full size arrow-block and pg-up/down. And it just cost 1/4 of the Moonlander. No per-key dedicated backlight, no programmable ARM Cortex or any other thrills, it's just a simple, comfortable, plug in and start using keyboard. I wish they offered an even cheaper version without the silly Mouse in the package.

It has a reputation for bad build quality but i've been lucky with mine. Also be careful to not loose the wireless dongle as the keyboard becomes a brick without it.
