I'm still watching for a few parts that I don't have. A supplies tray and stack of fashion stitch cams (which the machine I got includes) just went for $80.
I'm also watching out for a nice Elna 1 "Grasshopper" machine. It's a really nice ultra-portable, only a bit larger than the famous Singer 221 "Featherweight". It's got a few up on the featherwieight, though, in that it's lighter and features a free-arm (which, like the Supermatic, fits into the case to form a flat work table).
