Well, I only read the very first and very last posts, but asking for a 20% "bonus" for an original MM seems reasonable to me. Everyone of us will have a different opinion on what "original" vs "repro" brings. To me it adds value, even against NIB MMr. To some it would add more, to others nothing - the new one having newer technology: the repro could be better in many aspects - who knows? Opinions will change once the new MMr "floods" the market.
In the meantime, give the OP a break...GLWS or GLWKI (keeping it )
And I have absolutely no horse in that game. Although I enjoy the game, I don't own it, never did, and don't wish to - still above my price range.
