I had my Viking Scandinavia 400 sewing/embroidery machine serviced last Dec. One shop (large, national chain) wanted $145.00 for cleaning/tune up. I took it to my LQS, whose DH does Viking repairs and he charged me $69.00 for clean/repair. He also replaced the motherboard, which went "belly up" NINE days before it was out of warranty! Didn't even charge for labor on that, so no charge there. It sews like a dream now!
