I've grown interested in the retooled Unicron toy. There are only two versions I do like, being the 2011 Hasbro (Amazon) and the Takara 2010 toy. Both have their positive to me, but could someone steer me in the direction where I could find the cheapest of either of these 2? I've been looking around, it came out a long while ago, but I could use some help. Thanks.
