Yes $882... nobody ever said ergo life was easy.
Speaking of not easy, here is one of the $1800 IBM things.. https://www.ebay.com/itm/234254656786
My torso has only the two arms/hands, as one usually does. And I do likely have $1800 invested in my dozen other IBM keyboards. If I had thought this keyboard/torso maths out better I probably would have that thing in the link, and not all these other things.
