I was thinking about up-grading Aiko....but since I got her as a freebie.....I am not quite sure what the differences from buying her would be. I have always bought the up-grades for stuff like the Mil Dogs and the Dragon....so I haven't a clue as to what they lack as "LE" figures?

Morphs, mainly. Aiko 3 LE has a very limited amount of morphs.

Well, the LE version of Aiko, like many other LE versions lacks the full morphset and texture maps that one gets with the for-sale version. The Morphs and Maps package for Aiko, (that used to be called Aiko Complete.) gives you higher resolution texture maps, a full morph set with all the character making morphs like face shaping and body shaping morphs. It also comes with the A3 to SP figure so you can have Aiko's head on a body that will wear Steph Petite clothing. And the Aiko 3 Cr2 that comes with the package has channels for injecting other morphs like the ones provided in the A3/H3 horns and morph expansion.

Thanks For the info guys.....very much appreciated.(:

Note that Aiko doesn't use injectable morphs for the standard set; she's the old-style morphs-in-the-CR2, which makes her a bit heavy on memory usage. The A3-to-SP3 figure needs the SP3 INJ morphs.
