Just as a matter of market feedback:
Disappointing level of interest over here for the exact reason that I got one for 80 Euro's, home delivered including box , charger, cover and unused headphones.

As for the "sailors":
suffering the Sailfish X installation procedure evokes feelings the opposite of my romanticized image of being out sailing.
So I would have gladly paid your asking price + transport cost if it came with Sailfish OS pre-installed.
