I have a Sapphire 850 and love it. I started sewing on a Montgomery Ward machine in 1975. That one finally broke down in 2007. Bought a Pfaff and hated it. Kept it for 6 months then traded it in for the Sapphire and never looked back. I cant believe how easy it is to sew with. The foot automatically drops and lifts when needed. The other day I was sewing on my DGD's little machine and was sitting there waiting for the foot to drop....then realized I had to manually drop it.....duh.
