Earlier quoted context omitted.
Datahand keyboards used to cost $500-$1000 depending on the model and time of purchase.
Thanks for the interesting rabbit hole. I’ve been using a split ortho keyboard and while I’m quite happy with it I think there’s a small bit of FOMO whenever I see a unique design. Applies to the Topre and the Datahand equally: would be curious to try them, but probably not enough to procure one.
