When my original Duetto arrived, I got it out of the shipping box, unpacked everything, took all the protective film off, installed the loose parts, filled the reservoir, went to plug it in, and... discovered it was a 20 amp model, when I'd ordered a 15 amp. I don't even have a 20 amp outlet

It took me two weeks to get a replacement, because I had to ship the original one back before they'd send out a new one. Now THAT was a long wait.
All you new Duetto II owners are in for a treat. I am very jealous of the new features, and wish some of them had been included in the original model. The steam boiler PID isn't such a huge deal since I only have it turned on for half an hour every day. I am interested in making the heat dissipation modifications to my Duetto, as well as replacing the tacky original feet with the new ones, though.
