What an odd thing. I know one friend who has the non-embroidery version and her friend has the embroidery module and they both love their current machines.
So crossing my fingers and wishing you luck!
I have a modern 820 -- both the 760/770 ladies were previous owners of that exact same machine and neither of them liked it, so it got passed down to me. There are days when it is cranky and temperamental, but other days when it is just a dream
