I agree with whoever said to take it back to the service center. The machine I use most of the time is much older than 25 years, and I wouldn't give it up for anything!. I have had 3 new machines, (over$500 each) and now my daughters have them! What ever you decide, I wish you good luck. I am sure you will enjoy quilting. You will receive lots of encouragement here on this board.
