My Juki 2010Q is sitting on the floor, and I have not used it in several years. I got frustrated with the foot pedal, and bought an industrial Juki 8700 to replace it. It's got a servo motor, so can sew super slow (along with super fast, but when most seams are under 3" long, you never go that fast). I have the control set quite low. It feeds remarkably well, straight and curves. I sew on bindings on by machine and it does that very well too. I also love that I can get at the bobbin from underneath, so I have a sew steady decal on top that only has an cutout big enough to accommodate the feed dogs.
The drawback is it's very heavy and does need to be in a special table. But it never moves and since the food pedal is like a treadle, that never moves around either. I probably sew 10-30 hours a week on it, and it's by far my favorite machine for piecing.
