I wanted a machine to play around with to see if I could restore one before tackling my super special to me Singer 15-88. Bid on a 128 in a bentwood case at shopgoodwill.com. The ad stated "repair/parts" so I figured if I got it inexpensively enough, I couldn't lose if I really botched it up. Mine was the only bid at $9.99 and with local tax and handling I paid a whopping $11.43. Figured if I could refurb her, I could sell her on Craig's List and recoup my investment. Got it home and it was in beautiful condition. Dusty and linty and the case was grundgy but I did a COA on the machine and refinished the case and now I'm not about to part with her LOL So I think maybe the "repair/parts" thing is a CYA on the part of shopgoodwill. If they said it works, someone would buy it and find the tension needs adjusting then try to return it. Maybe?
