She says Singer was bought out a long time ago, and now they are worhless. What do you think, is she right?
My sewing machine dealer told me the same thing, but it's been about ten years since then. My dealer's explanation wasn't that they were bought out, but that they had outsourced manufacturing and that quality-control had slipped. I have no idea how accurate this was, or whether it's still is a relevant criticism of Singer, but I can definitely report hearing the same thing about Singer being a "worthless" brand.
In terms of brand recommendations, I've had the same very basic Janome for almost 12 years and use it for all of my sewing and all of my machine quilting. When I get a new machine for myself, it will definitely be another Janome.
