Whichever machine you choose be sure to run test pieces to see what happens to your 1/4" seams. I have an 10-year-old Bernina that is heavy. I bought a $200 Kenmore to take to class. It had a 1/4" foot on it and the seams seemed to match my Bernina's. However, after a class of a quilt with rows of triangles, my Kenmore's rows were shorter than the ones I did on the Bernina at home. I gave the Kenmore to my niece and bought a new small Bernina on a close-out sale. I love the new 1/4" foot with the machine and my seams are identical on both machines.
