My wife and I have collected machines that do decorative and other non straight stitches. She does crafts and I decorate things with the patterns so we've amassed quite a few machines. Some we have and are going to rehome since even though they are good machines they don't add anything different or unique to the stable.
We've been looking at Singer Touch and Sews because they can be set up for chain stitches. But I loathe plastic gears and have heard that some of the earliest ones have steel or metal gears. What I'd like to ask is which T & S models would have, or be most likely to have metal gears.
Knowing that would reduce the trial and error part considerably.
