I would not part with my 770 QE. I also purchased mine on sale so the embroidery module came free…I have played around with it a few times but i am going to play around with embroidery more this winter.
My 770 sits in a cabinet so I have plenty of space to construct large quilts while also having the ability to FMQ projects. While I am not a garment sewer, I do use some of the extra stitch options and a couple of specialized feet t for making drapes, pillows and appliqué projects. For me, the 770 is a workhorse and my “go to” machine. I do have two Janome machines that are also great …
