Please stay with the Bernina
You have used the Bernina and you will not be pleased with another manufacture. If you have a Bernina dealer, your service, if needed, should be a breeze as Bernina dealers are required to have company trained service available. Nothing sews like a Bernina. I am sure the Viking you are to the Bernina 530 has more features, because they are different models. Yes, the Bernina cost more. Compare the Viking to the Bernina 830 and see the difference.
