My girlfriend's aunt has a Dutchie.
Having borrowed it for a week, I would avoid them, personally.
The build quality is so-so... the frame seems good, but the finishing kit is cheap stuff - the brake levers have a disconcerting amount of flex, and the dynamo lights are flimsy. There's an amount of corrosion on the fittings and rack which is worrying considering the bike is about six months old, has barely been ridden, and is kept in a dry garage. There's absolutely no attempt at saving weight - everything is steel - the consequence being that the bike weighs well over 20kg.
The handling is bizarre - your hands are behind the steering axis, so it feels extremely skittish, even when you get used to it. It's not even that comfortable - I ended up with a bruised arse after a relatively short 10-mile-a-day week.
TBH if you want a classic-looking bike, I would go for a Halfords Real Classic (which a friend of mine has - cheaper, much lighter, much better to ride and equally well-built as the Dutchie) or spend a little more money and get a Pashley. Or do what I did for my girlfriend - restore a Raleigh Caprice with modern brakes, aluminium components etc and get something lighter and quicker than any of the above.
