Redco is best if new color = new character. ( New BIO and all) Second best if new color = "show accuracy". (Dream Project, eHobby etc.) Also Diaclone colors as new Cybertrons/Destrons. Ultra Magnus has been way over used. Third best reason = power upgrade, if HAS/TAK unwilling to create new mold. (results vary from outstanding to poor) :huh Fourth best reason is "Universe" and this is okay if the TF is cheap. Some of these Transformers make me laugh. Back from the dead zombies! Good material here! What I don't like is when the above is used with statues. Also, when NO CHANGES are made except the packaging. At the end of the day: If the Redeco makes you happy and you want to buy it, do so. If not, don't. You will make it easier for those who do.
