I have a Pfaff expressions 2.0 that is wonderful to quilt on. It has a 10 inch throat and I can easily quilt a king size. For piecing I use a little Brother sewing/embroidery machine. It beeps when the bobbin is running out or the top thread has broken or run out, has a button to cut upper and lower thread. I got it for Christmas but hadn't had a chance to use it yet, then my Pfaff went in for servicing and I used it to piece and I love it
