If your old singer is still in good shape,maybe just buy an embroidery only machine.I bought an embroidery/sewing machine.I still use the sewing part of it but not much the embroidery part.It can't be upgraded.But,a new embroidery machine might be in my future.Maybe.I also have several old singers I have bought at auctions and use several on a regular basis.No bells and whistles though.But workhorses.Anyway,just my thoughts.
