Today, at an estate sale, I saw a Necchi Supernova with the cool 3 sets of feed dogs wheels listed as an industrial sewing machine with cabinet and all accessories for $300. Didn't have all the presser feet, only 3, but wait it gets better. They said they contacted the Necchi manufacturing site which is where they got the value from and it was lower than the factory quoted them plus were told it dated from the 40s. I want to know how they contacted the manufacturer. I think they looked on Fleabay. It's industrial because their mom sewed upholstery fabric on it when she recovered the couch. When asked if I was interested, I said no thanks and gently suggested it was overpriced.
Oh well, not sorry I let that one remain in place.
