I have the Brother PE 770, I have the 4x4, 5x7 and the 12x 5 hoops.
My husband and I had the rational thinking that if I already had a sewing machine (s). Why not get one just dedicated to embroidery. Besides less wear and tear on it, if it only has one purpose. And another plus is I can work on a quilt and do an embroidery project at the same time.
