My daughter has had two Singers that went bad for her and one was a Quantum. The Singers are not the machines they used to be. Look up the models you are interested in on the internet and read the reviews. Then, buy from some place where you can return the machine if you don't like it. My little Brother I got from Walmart, is still sewing good 10 years later. It does pull to the side, but as long as I know that, I can adjust the way I hold the material. I have an inexpensive Janome that has a better stitch, but I don't use it too often because it threads differently from my two Brothers and uses a different bobbin. Pfaff with the walking foot built in was a machine I thought I would like to have, but I just don't need another machine.
