We've got a 1222se. Bought used at a sewing machine repair place about 15 years ago with several feet and all of the original manuals. It hasn't been used much since then, partly because my mom never got the hang of adjusting tension. When a Pfaff shop opened here it got a tune-up, and then was repaired when the power button broke. Luckily, the guy had a donor machine because you can't get a new power switch. Once I started learning about sewing machines, I figured out how to set its tension properly. It does sew like a dream, and with the electronics it has finer control than machines without a brain.
It is the most modern, and market valuable, machine we've got. Until something breaks. Then it is probably a doorstop. It is also the only free-arm machine in our modest herd.
I don't use it very often. I'd rather use my 1975 Kenmore in a table, because I like the table and I'm not afraid of breaking the machine.
