I don't know anything about that particular machine, but I have a Pfaff Expression 2.0 that I love. I bought mine 5 years ago and have just finished my 100th quilt on it.
I think if I were you, I would sew on the machine and see what you thought. I'd also have your wife sew on it. I can tell you that the owner's manual on mine is very good. I can figure anything out that I need to.
There are many Pfaff owners here. I assume you will get more answers, probably from folks who have that actual machine.
Good luck with your decision.
