Well, I'd buy Voyager, too ... but yeah, DS9 comes first on my wishlist.
Yeah, I don't think I could even say this. I'd watch it. Maybe rent it. Maybe buy some of the latter seasons but Voyager is just a show I watch when its on. And even then Im more likely to change the channel than watch it all.
DS9 on the other hand, I go back and rewatch that all the time, just like TNG.
I'd rather they release Ent. I'd love to watch Season 4 in Hi-Def, especially if they give it a generous special feature treatment (which considering its HD already, is really all they need to do).
