For quilting I use a Pfaff Expression 2.0. I LOVE the 9" throat, the IDT, and the smooth stitching. It also has an adjustable lock for the pressure foot down position for FMQ. I wish it had a low bobbin sensor; they did a visible drop in bobbin. Paid about $1400 on year end close out. Pfaff makes an Expression 3.0and 4.0 with more features than I have (thread cutter and knee lift) plus more stitches. I have a Pfaff 7530 that I use for every day sewing. They both sit ready to go at all times, and they get regular workouts. I always have a quilt going, and make a lot of clothes for my 2 year old grand daughter.
The only buyer's remorse I've had is that I didn't bite the bullet and get a 4.0 at the time. Prices have come down since then (2 yrs).
