I'm kicking around a couple of possible sewing machines I have access to.
My aunt had a Singer Model 750. I can have it now but I don't recall ever hearing a good word from anyone about this thing. I know she paid a lot of money for it in about 1970, and it had all the bells and whistles you could get. Still does. But when my mother got it, she never liked it. (She doesn't really recall why, she just had trouble with it. ) She said a tech told her the presser foot was worn out or something like that. My wife had one similar that was her mother's and had a lot of trouble with the tensions.
I also may have access to a 40's Necchi. I think it's a BU like this:
I'm going to try to get the Necchi, but was wondering about the Singer. Should I bother with it?
