Pfaff Quilt Expressions 4.0
The large harp space and my experience with a Pfaff 5770 is the main reason I bought this machine.
It is fine for simple sewing and piecing but will not free motion quilt without going into the repair shop. The machine stalls, the thread breaks and the tension slips. The needle threader has broken three times, the blade in the thread cutter has fallen off. The light over the needle is shorted out and is usually burned out.
This machine is worthless as a FMQ machine. I bought it on the basis of the Pfaff reputation of the past and have had to finish do my quilting on my Brother machine bought from Costco for around $150.
