I would find a vintage Singer 301 or 301A. If your lucky you will find one for under $100.00 dollars but they are worth twice that amount. I have found several for $25.00 to $50.00. Try Craigslist or Yahoo group SewItsForSale. They are the bigger sister to the Featherweight and have been around for years doing their job without problems. They sew beautifully and are light enough to be taken to classes and are easy to maintain yourself without having to pay to have them annually serviced. No computer chips or boards to have to deal with and they are heavy enough that they don't bounce around the table when you have your pedal to the metal.
