Ebay isnt exactly the "market" i go by.
yes i realize it isnt something so totally rare that nobody can get.. but theres alot of factors that go into play with "value" to people..
1) Location.. How hard is it to find said item where you live
2) The Want.. How bad does said person want said item
3) Memorys.. Some people pay crazy money for things that REMIND them of things like childhood.. we all do it now, arcade machines.. some of us spend INSANE ammounts on this "hobby".. yet our payoff for the most part? to play old games we used to play as youngsters..
Ebay IS where most places base there prices on..
1) Location - Not an issue anymore. If I want it, I'll pay for the shipping.
2) Want - If your price is too high, someone else is selling one on ebay.
3) Comparing an Arcade game to a console is crazy. As finding your favourite Arcade game is much harder to find. Especially one in good conditon. I can find a console game in my local classified or on ebay.
Plus, if the Arcade is in your area, people pay a higher price for it, as they don;t have to pay for shipping.
