A few years ago I got a Pfaff Quilt Expressions 2.0. It's a lovely machine, but I don't love it as much as its predecessor, a 30yo Pfaff 1467. It has an 11in harp (LOVE), needle down, auto foot-lift in needle-down for pivoting (LOVE), and about a zillion stitches. Despite the lower level of love I have for this machine, I'll still not sew before I pull out a back-up machine. This machine is no longer in their line-up. I added this to give you points to consider on whatever machines you do look at
My dislikes:
The empty-bobbin warning. My old machine simply turned on a light. This one brings my sewing to an abrupt halt. If I turn off the bobbin warning it will immediately repeat it. I can start sewing again without turning it off, but whether or not it repeats this rudeness is hit-or-miss. Might do it multiple times, or not at all. There are still yards of thread left when this rudeness begins, so it can get very annoying.
The delicate nature of this machine. I've already had to have repairs done because it got too linty, overheated, and froze up. My fault because my previous project had been very fuzzy and I had not attempted to clean it out. But, there IS no way to really clean it out. All the under-space is inaccessible. It MUST have it's yearly spa treatment. My previous machine went in for care about 3 times in 30 yrs.
Hand space around the needle area. There is none. There is so much automatic crap built into it that there is no room left to get your hands under there to do something as simple as change the needle. Must have the screwdriver to reach the needle screw, and must use the supplied seam-jumper with a hole for the needle to get the needle into position.
