I love my Sapphire 875 too!! I used to sell Husqvarna and Singers. I fell in love with the 870 and bought one, then traded up to the 875 when it came out.
I have a Pfaff 1222E that's about 35 years old; I bought it used about 4 years ago and that's what I was using for quilting until the Sapphire came home with me.
