I'm not wild about the refurbs in general - some have more appeal than others. I do know if you want to do anything else with it - like treadle or HC you may have to use a side winder for bobbins - not always but more often than not. How ever the 66s in general are nice machines - a well used one is really nice. Look at all that harp space!!! If the price is right buy it, clean it up and beat it to death - I bet you can't - nobody else will have one like it.
