Hello there. Without having the actual item on hand, is there a way to tell if a G1 Transformer is a knock-off or not? Several ebay listings do say KO and some do not. I'm assuming the KO ones are knock-offs. Obviously, the ones that look like the TRU anniversary encore reissues are genuine. I've seen several Sunstreaker, Wheeljack, and Mirage Transformers in what look like original G1 packaging, and some in same packaging but with Japanese writings. The Decepticon Skywarp and Thundercracker duel package I just received are an Encore package and in Japanese writing. Both toy's look 100% genuine to me. Also, what's the difference between a Transformer "repaint" and a knock-off? I've noticed several knock-offs are repaints and some repaints are not. In my search for Sunstreaker, I've asked the seller the question, but how do I know if I'm getting the genuine article?
