Oh Momwood, you've got an awesome machine, but I understand how you would feel overwhelmed at first. I got a 440 last year and just upgraded to a 730E. The manuals are not a lot of help, but if you take it slowly, you can get it. What is overwhelming you? the regular sewing or the embroidery? If it is the embroidery, I was too! But, first acquaint yourself with the machine with regular sewing and then move on to the embroidery. I never though i would want the embroidery, but I have now done everything from towels to a messenger bag!
I joined the Yahoo group for Bernina owners and they have been a tremendous help! I suggest you try that out also.
