I love my SewEZ - I got it for my Viking Topaz 20. They come with the cutout for your machine, so it sits down into it for sewing/quilting and I got the extra wood insert to set the machine on top to do the embroidery. Not sure what you consider an arm and a leg. It was $300.00 but it is wonderful. And I got it so fast - it was less than a week from the time I placed the order on-line.
