I use two of them. My Viking is my go-to machine for garment construction or home dec sewing and my favorite for buttonholes. My Pfaff is used for quilting. I just acquired a new featherweight 221 but I haven't even cleaned it up yet. Over and above that, I have two other machines that I have kept because no one really wanted them but I never use them--an Elna and an old Nelco.
