I think the reason people complain about things like this is because their parents never taught them about supply vs. demand. If you've got 5 donkey kong pcb's and they all sell out at 100 bucks, and then 5 more people email you looking for them, it's not rocket science to figure out that the boards are actually worth more. He's probably tired of being out of Donkey Kong boards, so he raised the price.
The value of Donkey Kong is rising anyways, even after the movie. The movie was made because Donkey Kong is a monster game. It always will be. They made the movie because Donkey Kong is BAD ASS and anything that's bad ass for 30 years is going to keep rising in value. It bumped a little bit when the movie came out and went back down, but years after the movie the value of the game is rising still while many more are in the basement price wise.
