I first got the idea from here. After seeing a set on Amazon for a fair price and having some extra dough to burn on an Amazon card, I picked up a set of these things for potential customizing purposes. Hey, if nothing else, my niece has something to play with next time she drops in. These things are almost all ratcheting joints. Stiff, too. Granted, some of the colors here are garish, but I'd imagine the lighter ones can be dyed (though I fear warping would damage the key component that prompted their procurement). But I'm seeing tons of potential here, particularly for people like me who really don't like the idea of dismantling Transformers to build new ones The question is, have any of you used these before? I'm thinking of using them in a scratch-build in the near future. I'm also not sure of the type of plastic used here, so painting is iffy. Then again, these are joints we're talking about.
