Congratulations. I think you will love it. I have the 830 (835 pre-cursor) and love mine.
My tip is watch which way you load your thread. For the 830 you need to have the spool spinning clockwise or towards you when it is horizontal ( which means the thread unreels counter clockwise if you were to manually unwind it). This means I need to put most thread spools on the machine upside down - no big deal it just looks odd at first.
