I take my machines to my Elna dealer about once a year, depending on when I go down to Fresno. I trust him and my machines are always taken care of. I've referred several people to him and they've always told me that their machines haven't run that well in years. If you're not happy with the one that's servicing your machine, I would find someone else. If you belong to some kind of quilt group, ask members who they have service their machines.
