I've seen them vary in price. I have 3 treadles and I paid $40 each for 2 and $50 for the third one. 2 of them are in excellent condition and the third (which I paid the $50) needs some work. It's a coffin top and the coffin top is in rough shape. Mine are a late 1800 Singer, an early 1900 singer, and an early 1900 New Home (the coffin top). They really are worth what you are willing to pay for them. There is one in town here that I went to look at - she wanted $150 and both the cabinet and machine looked horrible. I saw one on craigslist that was free to whoever could pick it up by a certain day (missed that one, darn it!). If you're patient, you can usually get a good deal on them. Like one of the guys I bought mine from said, they made thousands of those machines.
