It could be way, way cheaper than what it is. It's impressive what he's gotten done on his own; the devices even seem to be hand soldered. But if it was properly made even in a modestly sized run (<10000 units), laid out on a proper custom board instead of using breadboard breakouts, the cost would be down to 1/2 or even less. He really needs to find some industry partners. Even with just wave soldered breakout connectors and cheapo non-reinforced ABS injection molded cases it'd be waaaay cheaper.
