I haven't had a Bernette, but have had several Berninas. Berninas are a bit different than other machines but i've used them so long that a lot of things are natural to me now. I did notice when I bought a 475 a few years ago that many things were the same as my 30 year old Bernina which made things easier.
I've always bought from a store so I got the free user classes. They were very helpful. You might try finding some of those to help you get started.
