I have the same serger, mine is about 8 or 9 years old and the motor has seized. The replacement motor is no longer available. It was a good serger but I would not buy another one. My DH took it apart and said that the gear assembly is wearing and doesn't seem well designed to him. It has not been used for an extended amount of time either. $400 seems like a lot to me for an older model machine that only cost $800 to start with. I am planning on buying a Baby Lock to replace it.
