I don't know which one fits Swiss sockets out of the box. But Digitec Galaxus always supplies a good adapter free of charge.

This one (for 566Fr) also includes the blender / thermoresist. With the other one, you only get the machine - there's no difference. You'll have to ask someone else about the logic - I've been looking at all the machines and prices this week and really can't see through the prices. I think this is a good deal - I ordered it. For the blender you would have to pay separately for 75Fr.
