Well, I do agree with what your saying about the Yammies, but it could be possible to make them just as detailed as a Hase. In doing so it does bridge a gap of models and toys, kind of what Taka was attempting in the 80\'s. Only Yamato is doing a better job of it.
I would have to say (for me personally) buying a toy is only a factor of gratification, not really being lazy or young. Models require time, diligence, and patience. A toy, well it\'s just a toy.
