I just bought a new Phaff that you need a doctorate degree to use, and the dealer told me not to use C&C thread. They sell Mettler thread. Even other shoppers in JoAnn's told me to buy Gutterman thread. (I ask questions of the shoppers in the fabric section sometimes, since I am so new to sewing (especially quilting.) I am so disappointed as I have always liked Coats and Clark, and I have resisted this information against it for many years. (My new machine isn't embroidery so that isn't the reason for not using C&C.) I am surprised to read here that C&C is just as expensive as the other brands. I've been fooled all this time.
