I am sorry to the lovers of Pfaff's but I did not like mine.
I had Janomes - my first machine I can't remember the model - then a 4800 and then a 9700 - then I wanted a machine with a bigger throat - didn't like the embroidery side of the 9700 - so sold that and got a Pfaff QE4. For me it was a bad mistake. Within a few months of keep trying to learn to love it - I gave up and got a Janome 6600. The difference was amazing - I love my 6600 and I also have a Janome Jem 720 for classes - workshops!
I guess it is like buying a car and my advice is go and test drive them before you buy !
