The trouble is, I think most would be willing to maybe 'snap together' the keys and such, but not find a local PCB factory and have them create the boards and such.

Also, the cost should be only ~$100 or less if the device requires DIY.

I tried to quickly find information on how to create this board, or how to buy it directly from somewhere, or just how much it may cost to DIY, and I didn't easily see that type of information.

Ultimately, this is the best keyboard in this thread for this class (very portable, configurable, split kb). This is even better than the Voyager due to the added thumb keys.
