The price is well within acceptable. Used sewing machines always vary a lot in prices, the last decades the Featherweight has kept it's value and I guess it will in the future. Your machine looks like a bit dirty, but will clean and shine up very well. The original decals and japanning looks nice. If the case isn't particularly smelly it's a major pluss, even if it needs a bit of attention. During the clean up process you will get to know your new machine much better.
