I have had a 403 for years and have done quilting with it until I moved up to a machine with a bigger throat/harp. Still have that machine and it will still likely outsew anything out there if you don't need the 'bells and whistles' found on the new machines. As to problems with the machine, go to a website called Vintage Siingers. They have a forum where you can ask questions and get advice on problems.
