I bought two machines off ebay in the last couple of years and they are wonderful. One is a basic Elna, nothing fancy, but what a little workhorse. I paid around 120.00 for it , which was a good deal.
Second, I bought a Brother Disney embroidery machine. It has lots of neat features and really nice built in stitches, that I use quite a bit. I haven't done much with the embroidery, but plan to. I paid in the 180.00 range for it. I had no problem with shipping and found the machines to be in excellent condition. I would shop for a machine on ebay again.
