I used the "Buy it now" option to make sure I got my copy of the original trilogy. I paid $ 71,- (incl. shipping), which is about € 60,- for three movies sent to my mailing address. Not a bad deal, considered these versions most likely will never see a release on DVD.

You can buy these DVD's for less if you're willing to go for the bidding part. But you could be outbid and rist the change to not 'win' the item you were bidding on and thus not obtaining the movies. But then again, these DVD's are on offer by more sellers (and even offered more than once by the same seller).
