I have the Silhouette and it works just fine with any scanner I have. However, if you want to cut lots of pieces for a quilt, you'd be better off with an Accuquilt, Sizzix or Fuse. Those dies will last a lot longer and will cut more than one layer at once.
I normally only cut fabric I from stuff I draw or take pictures of, anyway. That means I can use the drawing software I'm familiar with and send the SVG file to the Cameo. I do some greeting cards and that's mostly the use for the Silhouette. I can make stamps and use those stamps with fabric paint, or paint on fabric itself with the Silhouette. That the Brother cannot do.
