I have one of these machines. I have an Elna Stella and a 9000. The Stella is a smaller machine with a full size motor. That one I used for sewing my 3 boys denim overalls. The 9000 I used for lighter materials, no problems just habit. Both machines are in great working order. My local repairman said that I have 2 of the best machines ever made. He really liked them. The only problem I had with the 9000 was that one day it wanted to sew all by itself. I had to shut it off to stop it. Not a computer problem but a foot control problem. Repairman found a used one and everything is fine. Enjoy.
