Oh I'd buy Wheeljack! Now I'll have to go out hunting for him!
But I never bought Grimlock because he's supposed to turn into a dinosaur.
But Wheeljack is done almost exactly as he should be (as an Alternator) but with respect to the First Generation Transformers.
Meanwhile, it's nice of Hasbro to send out something else I want to buy at this economically sensitive time (Revenge of the Sith)
