I've had a few scores like that. Most recently (okay, a few years ago) an Elan 7NE and an EOS RT for about a third the going rate, primarily because of bad photos of the items, and little to no description. Both in perfect condition. Last year I received a box full of dead T90s for $24 and free shipping. Revived the first one by tapping it on the ground. Well, bashing it would be a better description...
