In the past I've avoided re-imported b/w pins, simply because I was always able to find a US market version of the title I was looking for. I now have a chance to purchase a re-imported game locally.
I feel like if you had two identical games, one being a US model 110v and the other being a Euro 230v, the US model should be more valuable to a US collector.
Conversely, if the buyer was in a European market they might pay more for a game originally designed for their market.
Therefore, this question is mainly intended for collectors; how much does a re-import affect the price? 0%, 5%, 10% ?
In my opinion, I'd rather have a game made for the US market, but would be willing to accept a re-import, however, I just don't want to overpay if there is a stigma about them here in the USA.
