I have ordered a Singer Quantum machine from HSN before and it sews great, I have never had a problem. I ordered it for the decorative stitches before I started quilting. I don't baby it either. I pull denim through it when it's too heavy to feed. I had a problem with the foot pedal (tiny hole in the air line) and the repairman said it was certainly a better made Singer, I must have bought it from a dealer. The stitches are as good quality as my Brother 1500 and my Janome. I don't know about the other machines sold there but my Singer Quantum was a great buy.
