I have a small strap and harness business. I sew 6 days a week and sometimes 7 dePending on orders. I sell around the world. I run 3 machines. They were all Brothers. I bought a new one Dec. 2014. It just started having problems so with the quality of Brother machines going in the toilet, I decided to give Singer a shot. Let me tell you, this 4432 is a great machine. Had some small issues out of the box. I think it got shook up in transit but I worked them all out within the hour. As some other folks, The auto needle thread device doesn't work well for me. Two reasons - I'm left handed and this and all others are built for righties. The second is the braided and bonded nylon thread I use is too thick for that little hook to grab easily. Absolutely no problem for me. This unit really streaks along. I tried sewing double thickness nylon webbing. I had to make one adjustment on the upper tension and that was it. This thing flies and sews great. I really recommend this.
