"LE" is usually "Limited Edition", I think, and means a character with a full-detail mesh, but a limited range of morphs. So the Millenium Cat LE doesnt have all the morphs that change the head and body shape to represent different breeds of cat. In the case of Aiko 3, the LE figure is the cr3 provided in the Base pack. As well as the reduced range of morphs, it lacks the prepared morph channels for Morph Injection of newly-created morphs. The complete version has these extra channels, but doesn't use morph injection for any of the supplied morphs. Some of them are pretty big. Full Aiho 3is just over 47MB Aiko 3 LE is a mere 10.9MB Aiko 3 BLANK, with no morphs at all, is 1.03MB Aiko 3 to SP is 39MB The nice thing about Aiko 3 to SP is that the figure will use conforming clothing made for Stephanie Petite, and there's some good stuff around. But you have to regard it as a sort of SP3 LE. (I don't think any of this answers the original question, but I hope somebody finds it useful. If you're interested in Aiko, or anime-style figures in general, have a look at the megathreads in the Developers forum.)
