The think the premium that these devices suffer from is how niche they are. Mechanical is relatively niche to begin with (programmers and gamers, mostly). Then you add the idea of making a single large investment for the good of your health, and the pool gets even thinner. Just think of all the garbage chairs that people sit on in front of their computer; let alone keyboards, which they barely think of (until they get RSI, that is).
I'm currently designing one that is a crossover between the characorder and a Logitech vertical mouse (but not actually a mouse), and I hope to make it cheap. It has been going poorly, to say the least. The biggest problem so far is smaller hands, multiple designs scrapped when put in front of such a person. Maybe I should take inspiration from Svalboard instead? Furthermore, Average Joe is not going to tolerate the massive dependency on layers that these keyboards often have, so I'm still fighting in my head with an approach for that.
