I have the Bernina 1150. I didn't go top of the line because I doubt that I'll ever need to do a cover stitch. I'm not sure I've even done a rolled hem. The Berninas are not self threader, but it's not hard once you know how to follow the diagram on the inside of the machine. Don't go bottom of the line no matter what you get. And take a class or something to get started. They are fun machines!
