Manufacturers make "special" machines for high end sellers such as Walmart, and on-line retailers such as QVC. The seller tells them what they want and the manufacturer makes it for them. They can be a really good machine or a piece of junk. It's a gamble. I use Pfaff or Babylock machines and I really love the Babylock for general sewing but it doesn't like to quilt. The Pfaff doesn't mind quilting and is a good general all over machine as well. I learned a long time ago not to buy the cheapest machine. I've worn our several of them and been aggravated to death by several more.
