Well at least with this its usually only a few hundred dollar mistake. And you also have to realize these things come and go. I wanted the original Bowen Batman statue, and for the longest that piece would sell for over 1k, but recently I've seen it selling at 300 give or take. These statues will never hold value completely, they don't have history, they aren't originals and they don't lend themselves to adding anything to the mythos the represent. Those three things tend to give art value. These will never have any of that.
Which is why I tell people to buy what they like, not the number on the bottom.
