i love those old singers. they're hard to find now and are typically pricey when they are in good shape.
i use a 1/4 foot, a walking foot, a curve master for curves, i have a quilting bar that can be used with any foot, i use some kinda foot that has a bar in the front for stitching in the ditch, i use an open toe foot, i use a darning foot for free motion, then i have a bunch of others that came with the machine that i've never used.
