OOO I've gone and done it again! Saw a locally advertised Singer Touch and Sew for sale for £60, and it appeared to be pristine - well, I took a punt on it and it is like brand new (its 51). I bought it from a lady whose elderly mother had 'given up' sewing, but from the look of it, she had never started! Some of the accessories were unopened in their original packing, and everything works a treat. I am more than impressed with the chainstitch option, makes a lovely attractive stitch on the underside. The feet and accessories are beautifully made and heavy. It was one of the last Singer models to be made in West Germany. It does have a few 'nylon' cogs in it , but these have hardly been touched!
Lots of playing and one happy customer - however I will say I had one years ago and it was a right mare!
