NIB may be the best option in future for private collectors.
A used title would need to be extremely good to fork out more than $3K for a 12+ year old pinnie.

I totally agree with you there. Thats why i have never forked out anymore than aprox $4,000 for any 2nd hand machines. Some titles, mostly later Bally titles, are way over-rated and way overpriced. Played alot of those, collected none of them. Just couldnt bring myself to overpay for a supposed A title when u can pick up much better playing games for between two and four thousand dollars max.
I dont mind collecting new Sterns now, cause a new AC/DC or X Men plays better than a Addams Family for example and people want $6500 for one in good nick. Addams is a great game, dont get me wrong, my wife wants one, but at the same price, STERN gets my money first.

In the USA, Addams Familys are much higher again compared to here. Gettin crazy over there.
