I have a Brother PC6500 for embroidery and the basting stitch. That is pretty much all I use it for. Vintage machines: Singer 301, Featherweight, 3 15-91's, Singer 404 Slant, Western Auto Wizard in 57 Chevy turquoise and white, Singer 31-15 industrial straight stitch and an Industrial Pfaff 138-6/21 BS Zig Zag that makes the most beautiful satin stitching. The 2 industrial machines fit the same table cutout so I switch them out as usage demands, and a Kenmore Serger.
I met one of my neighbors who collects vintage machines. She has found most of the vintage ones I have. She has quite a collection herself, but is preparing to sell them off due to her health. She can't move them around and use them any longer.
