Well, here it is, the machine I bought today. I finally found one at a great price:
From what I've read, this machine is kind of rare. Not that many were made so I was really glad to find one. It came in a case (finally, a machine NOT in a cabinet) and with all kinds of parts and attachments from another Bernina 117 (an entire plastic bin filled with parts such as gears, a complete bobbin winder assembly, and all kinds of other parts all in plastic baggies), an entire bag of presser feet and bobbins, the zig-zag plate, the manual copied and put into a folder with each page in a plastic sheath, etc.
The machine itself is in really great condition. I haven't sewn with it yet (I've only owned it for a few hours) but will do so tomorrow.
Sometimes when I buy these machines, I ask myself why. The last thing I need is another zig-zag. I guess I'm a collector. It feels strange.
Does it remind you of another machine? Yep, same here:
Anyway, there it is -- I finally found one.
