Then I would suggest either a Bernina or any machine more than 30 years old.
Your best bet is a machine that you can buy from family or friends so you have an idea how much mileage it’s got.
Old machines are better but it can be a problem with spare parts if it is an unusual model.
Send me a photo of a machine you are considering buying.
If you are planning to use it a lot I do suggest investing in a good machine. It’s worth it in the long run.
