Now this is funny I am retired and I am keeping my vintage machines from going into retirement! :lol: :lol: :lol:
Seriously I think their perception of retired is the model they did away with but replaced it with a newer version. Like the 301 went to the 401 etc., so it would be new in the box if that is the way they are presenting it.
Personally I would keep using the 301 and just save my money for a new machine that you really want. Sounds like you were threading it the wrong way, and the top tension might be a little loose. A lot of good information has been given on the 301 and you should be able to get it up and running perfect in no time!
