I have the Bernina 730 and the 830 and love them both.
My dealer is still teaching me things and he wants us to use
the machines all the time. Go with a dealer that cares about
you and makes certain that you can work everything on it.
I went with the Bernina dealer because after a couple of years he is still providing help and answering my questions. He is only a couple of blocks away so everytime
I need help and advice he is always there. I bet he is sick
of me but he still smiles and gets me through it. LOL
