I have the se 350, and wish I had waited for the upgraded 400. It will connect directly to the computer to download patterns. It has a wonderful stitch for regular sewing, although I usually just use it for embroidery. Easy to thread too. The only negetive is the limited 4" embroidery field. The PE 770 has a 5"x7" embroidery field. Occationally I find the larger design option would be desired.
