I bought one of those machines about 15 years ago and I love it. I have had no problems with it. We have a local man who repairs all brands of machines, so service is no problem. The local Singer dealer will repair them also. I wanted a Singer machine at the time and this was all I could afford. The local Singer dealer didn't have a machine for $150. The serger attachment does a pretty good job also. It has come in handy several times.
Sorry my little cheap machine isn't good enough for some of you, but I am happy with it. It does everything I need.
