I've heard some folks refer to that machine as a 'touch & swear' and then others think they are the greatest thing since sliced bread. Glad you are having relatively good luck with it. Have you had it in for a tune up recently? That might take care of some of your issues?
If you are looking for a totally mechanical machine, you may need to go vintage, still. Others here that are more familiar can tell you if there are new, non-computerized machines out there that are reliable and capable of FMQ. I don't machine quilt and wanted a computerized machine for some of the features they have.
You could jump over to the vintage machine section of the board and do a search with the 'fmq' term and see which of the vintage machines folks are using for that purpose as a start.
