I can't fault them for not making such a niche product at a large enough scale to make them readily available and cheap. I know we've become accustomed to that from other larger companies, but for a small company, that's either very risky or just not an option. So they just design cool stuff, make just enough so that they know they can safely sell them all and thus make a predictable ROI, and move onto the next cool thing. No pressure for growth or satisfying every potential customer. Sounds like the dream.
