I don't think Ultra Magnus is worth much G1, Reissue, and Hasbro... I remember watching a couple of MIB G1's go for under 100 bucks awhile back.
I just got an open G1 magnus mint missing a launcher and a missile for $40 w/shipping, so no I don't think its worth the same as a misb G1 magnus. Sorry man.
Reissues are generally more common than originals, so they tend to be worth less than a vintage release. It is certainly true of characters like Ultra Magnus where the reissue was quite widely distributed at the time of release - there's a whole lot of them out there. It is worth more than the US reissue one, though, for being a true and accurate representation of the original toy, not altered in any way to comply with modern US safety laws. That does put it up a bit for those who dislike the huge missiles on the reissue.
With all of Takara's 2010 hype, i'm a bit surprised they haven't solicited a reissue. The last one was what... late 2000? Early 2001?
That was never available for purchase during the G1 era. The only grey Astrotrain was a prototype that couldn't transform and who knows how many of them survived after all this time. I'd love to own that one, the arms even slide out
