The w and e keys are next to each other. Good job of fat fingering the keyboard and not catching it. At least they're not looking for someone to sow them a pair of socks. You have to work at it to make that mistake.
I am curious why they need a custom pair though..
The price on that 128 is pretty "optimistic". When you look at the sum of the parts, I would say somewhere in the $50 to $100 range would be a much more realistic price. I see a decent bentwood case and knee controller with the machine, that gets expensive quickly if you try to buy them on epay.
