Craigslist usually has several (or more) used machines for under $100. Some people think vintage machines are far superior to newer ones anyway. Flat bed machines seldom sell, so are quite cheap. I refurbish old sewing machines and can never get more than $50 for one. ( I never pay more than $25.) I give many of them away.....and they work perfectly. Don't be afraid to offer less, esp. if the machine has been listed for weeks, or months.
