I have the Babylock Quest Plus that has the built in walking foot so there are no tucks when quilting. A deciding factor was all the feet work with the PDQ and it came with a large table, so there was no added expense. Has a perfect straight stitch and almost 9" of space. The new Quest is called the Serenade. Also, have 2 Vikings that sew nicely, but would not get a machine without the PDQ (precision dual feed) or IDF (Pfaff's name).
