I thought I had too many until I read all the stories. I have six machines that cover light, medium, heavy and extra heavy sewing. Starting with a Singer 29k4, Singer 31-15, Singer 111w155, Juki 563, Singer 97-10, and a Landis #3. I will finish my collection when I find either a 441 clone or an Adler 205-370, and I might through in an Adler 30-7.
