My upgrades are always to vintage singers. I have 6 featherweights, a 1904 66 treadle, a 1951 15-91 that is a workhorse, a couple of 99s and several others. I have some modern Janomes that I use for monogramming and for making buttonholes, but my alltime favorites are my olden girls, ranging from 1936 to 1953.
