In search of Ducktales treasure...

Hey, anybody remember that first full-length Ducktales episode? I guess it was the pilot. It was really awesome and was about the Golden Suns...the animation was really cool and it was kind of dark and comic book-y. Ha, yeah and Scrooge starts hiccuping because he has "gold fever". I remember at the end, this huge sea of molten gold...that was classic stuff.
I had it taped *years* ago, but of course, now being semi-grown up, it's gone the way of the Cabbage Patch kids and my Mario lunchbox. :)
I would looooove to get this again.
Does anybody know if this is available anywhere? on Ebay? on vid? Does anyone have an old copy they'd be willing to sell?
