Have you owned a Pfaff before? Reason for asking is that the quality of the newer Pfaffs can be less than the older (made in Germany) Pfaffs. Someone who is not used to that "old Pfaff feel" probably won't notice and be totally happy with the new Pfaff.
I read in a review that there was an issue with the table not aligning properly and that the seams flip too easy. Don't know if that has been fixed. That was actually one of the reasons I did not go with that machine at the time I was researching.
Do you have a chance to test drive the machine? To me, that would be the final decision. How she feels- how she handles and how good a deal you can negotiate.
