The "I gotta make a lot of money today" fairy has bitten a whole bunch of sellers lately. And Goodwill is the leader of that pack. That machine should have been priced at $5 OBO to move it out, not $55. I was in Goodwill today, still trying to find a good FW in one where the sorters don't know what they are sorting through....and found a Singer Touch and Sew in dirty and terrible condition in a desk that was even worse for $39.99. I just looked at it and tch tched my aggravation and left. I had glanced at a couple of pretty decent sheets that would have done for a lining someday, but passed them by on my way out.
Back to the original subject; yes, $55 for a machine like that in bad condition is too high. Wait, you'll find what you're looking for and your joy will be what you are wanting to feel.
