It's $255 and doesn't come with any switches from what I can tell. Not the person you're responding to but I've heard good things about the UHK: https://ultimatehackingkeyboard.com/
The lack of Esc is just plain stupid and needlessly “special” for a hackers keyboard, especially with zero space constraints. The keys themselves I’m not a fan of, but that’s because nothing beats the buckling spring keys I’m used to - so not counting that against them. Build quality is great, however.
If you're not happy then build your own - or buy a unicomp board and replace the controller so you get the best of both worlds - buckling spring and programmable keyboard.
A big part of the appeal of the UHK is the agent, which lets you configure the keyboard any way you want. Not all keyboards let you do this, so it's often an apples to oranges comparison.
