as far as a seized up machine goes- the advantage to these all-metal machines is that you can remove the motor and drop the whole thing in a bucket of kerosene and soak it. Of course, you only do this to machines that are rusted or otherwise unsaveable, since this will trash your paint usually. I have a pink 221 and a purple 222, and think repainted FW are the cutest thing... if I saw a FW for 50 bucks I would be racing to get it.
