Well it's actually rather expensive. We are talking about perhaps 5 Euros per board, which is far to expensive for something only few people need.

What makes it expensive is that it needs galvanic isolation. So it's about the same number of parts you have in a fixed voltage power supply, you only need beefier components as you're dealing with lower voltages and therefore higher currents.
