Thanks all for the information. I will be going to look at a 15-91 today as I found one on Craigs list in a nearby town. The prices even includes a compact maple cabinet for $45 or OBO. It appears to be in very good condition. My plan is to use it for sewing but I would also like to have to option to use it for FMQing. I have a modern machine capable of almost everything but I'm not really happy with the straight stitch. I'm excite to get the machine. I will also be trying out my grandmother's treadle machine soon. My mom has had it in storage.
