I explained (politely) that $55 was a bit steep for a machine that had no foot pedal and therefore no way to test if it worked. And that the cabinet was pretty much a throw away. I said I would offer her $30 but understood if that was too low and she wanted to wait it out for a better offer. She responded that she would take that much so I'm going to pick 'er up on Friday.
Thanks, as always, for the input (everyone)
