I don't buy the money argument, price is not cost. I'm fairly convinced that the medical market is inflated at every level, ending on a premium. Ultrasonic devices may be as complex as he says, the dude is a reference. But I've just seen firefighters portable EKG monitor that they say cost a fortune, and it's mostly crap. Very bad cell reception, couldn't send data to the doctor. Not as sophisticated as an US echographer, just 7 probes, a LCD in a sturdy/friendly case; still pricey.
I'd bet a few dollars that any electronic company today can make something affordable, with better connectivity. It's just that the market allow for such prices.
