My DH surprised me with a Bernina 440QE with a BSR a couple of years ago. I almost fainted. I had no idea he was listening to me when I talked about this great new invention. You will love your machine. I know everyone is telling you to breathe easy and take the classes -- I agree, but also be sure to check out youtube for tutorials. I have learned a lot from youtube. Try searching both Bernina and your model number.
Good luck!
