Very interesting conversation going on here, I was just wondering if this is THE machine I need:
http://people.uta.fi/~hs62298/kuvia/singer/
It's for sale in a auction site, price starting from 50 euros, about 45 USD.
I have already decided my treadle will be 201, partly because they are not so readily available as 15's and Husqvarnas (Viking) around here. So there will be less temptations for me ;-)
Any opinions about this linked machine, seller says there is no rust and it is not jammed?
