I disagree with your thoughts , each to there own I guess
Did you have a bad experience with your NIB pins ?
To explain it politely, starting with Family Guy in 2007. Stern set up their USA build machines to only work on 60hz, a firmware thing.
Here is the interesting thing, machines that are sold overseas originally will still work if re-imported to the USA, without modification. I don't know why it is set up like this, but if anyone has any theories, throw them up here I am curious.
