The 66 was in production for a very long time and there were literally millions made. This is the most numerous of the Singer family. They aren't particularly valuable. The lovely decals are the big draw, along with the large throat area. It uses a 66 bobbin and they come in plastic or metal. The metal ones are probably a better fit. The light isn't a real problem. I recommend the plug style, LED, lights with the magnets from the internet for under $15, which are less than replacement vintage lights and give off 4 more times the light anyway. This machine could wear out 4 ladies in its lifetime, maybe more. They are easy to work on and good ones to learn to repair. I would recommend it.
