I have only bought 2 new machines in 60 years. The first was a Kenmore zig zag when I was a sophmore in college.
The second was a Pfaff 2040 ten years ago. It is the only electronic machine I have. Right now the part that covers the end of the machine won't stay attached. Of course, it is plastic. I haven't even tried to find a replacement part yet. Duct tape is curently holding it in place. I have seven other machines all purchased used. I agree with those who offered suggestions of gong to a sewing machine/vac dealer (NOT A QUILT SHOP) and look for a good used machine. The cost will be much better for the money. Unfortunately many of the newer machines have a lot of plastic in them. Ask the repair technetian which one he sees the most often..Then don't buy that model. My oldest machine that I use regularly is a 1936 model Pfaff. My mother sews on her 1953 model Pfaff that has all the fancy stiches you would ever need. It has only been in the shop one since 1953.
