I'm sure the price will drop if they catch on but, assuming it's basically a hacked jet-ski with a hose & harness attached to it, they still won't be cheap. A jet ski can set you back anywhere from $10k - $50k around here, so it's still a luxury item for most.

Ah. The engine is from a jet ski, you mean? You might not be able to buy one for cheap, but you will be able to rent one for $20, so it's still good.
