I found a Necchi BU Supernova a few months ago, with all the attachments, cams, cam box, written instructions from the owner, TONS of bobbins, tools....It's my new fave. Not a treadle, but a great machine. $50 in a cabinet. I thought it was a bit much to spend on a machine, but I'm finding that it was a pretty good deal. I don't think the seller knew too much about his mother's sewing machine, except that she had it serviced regularly and had used it as long as he could remember. (Doing the happy dance)
