Thanks for all the information. I'm anxious to get my machine next week. Not sure yet if I'm going to keep my Pfaff 7570 or sell it. The owner of the store said he'd buy it, but don't know yet about a price. I've always liked that machine. I think I'll 'drive' the 5.0 for a while, then decide, since the 7570 is not a trade-in.
Happy New Year!
