My friend is a believer in Berninas and gave me her 820 when she replaced it with a 770. She just didn't click with the 820 but loves the 770. She uses a different system (non-Bernina) for embroidery. She felt the 820 was fussy with threads, she does a lot of with fancy threads and materials. I'm doing just fine with the 820 so all is well! I've been sewing on a vintage machine older than I am for the last couple of decades so it is fun for me working with a "sewing computer" from this century.
