Congrats on your new machine! I have the Janome 6500 now for 2 years and love it. But I did break my auto threader somehow and haven't taken it in yet to get it fixed, I miss it. You'll love yours. It took me some time to get the hang of it, but worth the effort.
You'll be stitching up a storm and trying all your new fancy stitches for certain.
