Gravion And Gravion Zwei Anime Box Sets

Gravion and Zwei original box sets from ADV. This is a pretty good mecha anime and very reminiscent of power rangers or voltron. Gravion has all booklets and stickers, no art box sleeve, the first dvd was available with or without the box. Zwei is missing booklets. Otherwise, all the dvds, cases, and slips are in perfect condition. Tried doing some research on these, but all i can find was a later rerelease of all 6 dvds in a single case in terms of overall value. While Gravion info was plentiful, the Zwei box set was sparse. So I'm just going to value this with the info I got with the gravion set and what the full 6 dvd re-release go for which is 60. I'll look to find if there is a box art for gravion but since the first dvd in the set was sold with either a box or just on its own, i doubt i have it, since many times I just didn't know at the time which volume would have the box sleeve.
