Buy it!
Good suggestion, but people are funny.
If the original owner was told that this item could be extremely valuable to the right buyer, they would just laugh. If you bought it for $100 and then sold it for a huge profit, what would they then say? Would they come after you for the money? What then, a lawsuit? Would you have to document everything on paper to protect yourself? You could give someone twice what they think it is worth, sell it for a profit, and then they come after you, saying you swindled them.
Money makes people do strange things. Just look at Stephen Lett and his May broadcast.
