I have a 758 touch & sew that I bought new in the mid 70's and except for the fact that the after market bobbins don't wind properly I have never been disappointed with it. The last time it was serviced I was told that I had a good machine - it is old and has been used a lot so sooner or later something is bound to need repaired. Wouldn't consider buying a new one now though. Love the 15 that I picked up recently.
