The moral of the story is "its worth at a certain time what someone else is willing to pay for it, no more and no less:
so what you paid is somewhat irrelevant to what you paid since that transaction occurred in a different time and market.
When I look at my snakes, or Super Hypo Tangerine Geckos, I know what they are worth, and would never sell them for a penny less than what they are worth.
Reptiles only go too cheap, when a seller is too desperate for the cash and lets them go. But this is the market place.
