Just picking up on a chat from a while back on 'semi-industrial' desktop. Agree with whoever called this out as misleading, but dropping in as a reminder,
I got hold of a Pfaff 1222 a few weeks back, and it's a pretty remarkable machine for it's size. It was completely gunked up, with a few broken components and the usual build-up of compacted thread and fluff. It's It's largely mechanical, so super-easy to work on, order spare parts, clean, and repair.
It was made in '78 and is solid-as, weighs possible 3x a modern domestic machine. The motor is also way more powerful than a modern domestic, but still easier to control/use than an industrial. It has the option to drop-down a small walking foot, something Pfaff called IDT 'Integrated Dual Feed'. It does really good quality bar-tacks and zig-zags, plus a host of other stitches, some ornamental/fancy and others for hem-tacks etc, but not used any of these (and probably wont either). Having used an industrial bar-tack, there's definitely a convenience in using this machine for lighter-weight materials.
Thought I'd post here incase anyone was looking into these types of machine - would definitely recommend for a highly versatile desktop. There's a couple of variants and later models, which essentially got more electronics as time went one.
