I just bought a 301 mint condition except no bobbin case at a tag sale for 30.00 and invested over 100 to get her working properly and it was well worth it...Love her...
Then I just bought a 301A in cabinet off Craigs list for 110.00...in mint condition..only needed a good oiling and again well worth it...
I say no matter get it...It's worth any investment to get her running
