That is the cheapest I've seen one go for used, and that seller should be kicking himself for pricing it too low. With the yearly price increases from AMB, and the fact that they don't wear out, there is no reason to discount much from new plus the transfer fee.
AMB has the transponder market locked up and can sqeeze the market for what it's worth.
