Bought two used Berninas. Artista 170 has been a joy, 670 did nothing but screw up. Finally gave the 670 with its embroidery module, all paperwork, USB stick, presser feet to a dealer and said 'Do with it what you want. I can't afford to keep paying a repair bill and have it break again 4-6 weeks later with normal use." I sew a lot and when it worked, the 670 was wonderful.
