I did consider the pfaff QE4. I saw some scary reviews about this model when it first came out (mostly about shredding thread and a defective take up). The main thing I didn't like about this model is that the bobbin cover is not flush with the front of the machine and I can see how the "bump" would flip seams the wrong way. I tried it out at a local dealer and it was really annoying. The 7700's bed and needle plate fit seamlessly together.
