Repaints happen..that is just a fact. Some are very minor, to the point it is hard to tell the difference between the repaint and the original. Some end up differing quite a bit from the original model. Sometimes Hasbro does it right and creates a demand for a figure, while other times they just sit on the shelves (I'm looking at you, Tuner Mudflap and Skids). For me, it is rare for me to buy a repaint because I enjoy transformers mostly for the transformation aspect, and it is no fun to have two figures that do the same thing. however, I will at times by a repaint if it offers enough differences to justify the character.
