look up pinpedia as they have a search engine that looks up the ebay sale history of pinballs world wide. Also comparing the US with us is not accurate and most DMD pins will be approx $500 to $1000 less than the selling price here in Aus.

hope that helps as a guide and maybe others will chime in

i did happen to have looked at the pinpedia rankings and information on the links for individual pinballs

and the values were severely off compared to what i was seeing but it makes it much more clear that i have someone backing up my hunch that the US market seems much more competitive if im not living in it.

and thanks for the advice:)
