I bought the cutest 301 a couple of weeks ago and cleaned it all up and she sews beautifully...this weekend I found another one...in a table...I don't know anything about the 401..but do watch for the bobbin case...make sure they know what it is...
I bought a 221 a while ago and the lady told me the bobbin case was broken...I bought the machine becasue the price was good but when i got it home I saw there was nothing wrong with the bobbin case ...it was the tension unit that was in pieces and I was able to put it all back together...
