I bought my 404 in '62. It's a straight stitcher. Has attachments for zigzag and buttonholes. In the early 70's I got a White zigzagging machine. In the 8o's obtained a White serger and later a White heavy duty "school machine." In the 90's, got a Janome MC4000 (computerized). DH found a Singer (1896) treadle (still not restored). Now I'm working on getting a Janome 6300 Quilting machine and table.
Let DD#2 use the Singer 404 (It's in a cabinet.) Now it is back home. The White zigzagger is still in good shape but doesn't get used very much. I carried it to classes that I taught. The Janome MC4000 is my go-to machine at the moment. And the White heavy duty school machine is the one I use to machine-quilt. Treadle machine is taking up valuable space in the sewing room. Have a new Janome serger. Old one is in a box packed to have it repaired and cleaned.
