Not sure on the machine youar looking at. I have a Phaff expression 2034 that is about five years old. I love love piecing on it. I have had no problem, and sews very well. I also have a Bernina 730 that I do embroidery on...but love piecing on the Phaff. Not sure this will help but I do not see you making the wrong decision if you go with the Phaff.
