I'm prepared to be corrected on my attitude toward this question, if anyone can explain my misunderstanding of this situation, but here goes:
My understanding is that most sewing machine brands are owned by holding companies these days. The machines are generally manufactured in China, in the one factory, and re - badged. This is especially true for the sergers. There are low - end and high - end designs in each brand, and you get what you pay for. I would prefer the Bernina because it is still a privately owned company and it is only the two low - end Bernina models that are made in China. Having said that, I don't own a Bernina or a Janome. I have Babylock, Pfaff, Brother and Husqvarna. The only one I'm disappointed with is the Pfaff as I have a communication problem between it and the computer so my embroidery section is limited.
