I have the one I learned to sew on in 1962. It belonged to my mother, it was a wedding present from her parents in 1950. When my parents asked me the one thing I wanted them to leave me - it was that sewing machine. It works better than my other machines that are so much newer. The cabinet your's is sitting in looks wonderful and I would think that is well worth the money. Leon is right - as it is pricey for the 15-91, but a lot of them are pretty worn, and this one appears to be in wonderful shape. And like oldmanquilts I wouldn't take any amount of money for mine. (I do have the button hole attachment, the zig zag attachment, and a thing they call an embroidery attachment. I also got the walking foot.)
