The reality is that you need to ask yourself wether you want a hobbyist' tool or a more common one for the same result.

Logitech's ergo k860 is affordable, has a palm rest (most mechanical keebs don't), and has an excellent ergonomical shape. And works right out of the box, with Bluetooth enabled.

The keys are membrane-based, which some may dislike because they are not mechanical - but it's actually more ergonomic, as they require much less pressure and travel length to achieve an input, meaning less wear on your fingers.
