I do not buy used. Someone has traded it in or sold it because it wasn't what they wanted, they wiped out, something broke and they said it was defective. I would buy something new, no one has F***ed up and you have the primo opportunity of doing that yourself. Or you can let yourself be taunted into buying a second hand item. Buying used or refurbished reminds me of that Big Bang episode with the chair they find on the street, bring it upstairs, and something is living in it, bites them, they take it back to the street and another group sees the bargain and take it upstairs as the audience sees the outline of the creature scurrying about.
