Most of the dvds of Sailor Moon on eBay are bootlegs or very expensive Out of Print dvds. I've heard rumors going around that Funimation was in talks to buy the rights to Sailor Moon in the USA and then re-dub the whole series. Then release them sometime mid to late next year.
They are also starting a new season I a new series based of sailor moon in Japan I believe. Naturally we will be stuck in the dark till it gets done airing there. It blows!
It's rare for them to do this, but they might get the rights to release it over here, before it ends airing in Japan. They will only do that if they think it's going to do very well over here.
