I'm sorry to hear you don't like the Record 730. I was just 19 when I bought this same sewing machine. I know I had a little instruction on it .... but mostly from the manual.
As for Bernina's being complicated to use ... I never found this one complicated, pretty simple with just a few knobs; but maybe the newer, computerized ones are harder to learn.
Good luck with getting your $$$$ back and finding a machine that will work for YOU!!!
