- an automatic sewing machine in school,
- an old electric one with "automatic" pattern (never used),
- another one that needs a new motor
- and a pure mechanical "Anker" sewing machine with zig-zag
I have to say that I prefer and recommend the last.
It has already lasted 50 years and there is no reason to assume it will stop working in the next 50 years.
And there is no risk of the machine suddenly starting and puncturing a finger while working on the needle.
