I don't know anything about the singer machines,but I can tell you I have 2 brothers machine and I am very pleased with them. The first one is qs9000 I like it and did free motion quilting and used the design stitiches on it. But like some of the other members mentioned I wanted a machine with a larger throat for larger quilts, so I search the internet for a good and reasonal price machine and I came across the PQ1500S machine and after studying the reviews I purchased it and am so happy I did. It is well the price I paid for it. $599.00 at an albrands.
