Also, check estate sales and newspaper. Sometime people will buy an nice high end machine and find they do not want to sew after all and want it gone at a reasonable price. And by all means, look for an all metal older machine vs the plastic ones made today. I don't see any of them being around 75-100 years from now and still sewing like a champ. You should be able to find a walking foot for your machine so do a computer search for one, might make all the difference with some adjustments to your present machine.
