I love vintage machines. If I had room (and money) I'd have a bunch and also one of the swell new Brother, Janome or Bernina top of the line sewing machines, and an embroidery machine and a sit down long arm and maybe a long arm on a frame. As it s, I have the four machines that are listed in my sig. The PQ gets used nearly every day since I use it for most piecing and all Fmq these days. The PC420 get used for anything that requires zigzag, decorative and utility stitches other than straight stitch or if I need to do some basic sewing when the PQ is set up for Fmq--saves having to switch feet. The featherweight doesn't get used as much, but I have a hand crank for it that I put on and sew away when the power goes out, or if I just want to spend some time sewing outside--otherwise I try to make sure it gets used a couple of times a month. The Vx560 is now only used as a backup when the PC420 is in the shop. It was my main quilter for many years before I found the used PQ.
