I bought an $800 serger and had to keep taking it back to the dealer to have them rethread it. I could never get the threads right. Never made a thing with it. It sits under my cutting table. Been there for 2-3 years. What a waste of money for me. Some people can do magic with them. If I could keep it threaded, maybe I would like it. The dealer became impatient with me because I brought it in so many times. Too hard for me. I like my sewing machine.
