I'm grabbing one of each type, FE, RID car and AM Jet at the moment, I've also managed to grab an AM car in a multi purchase of eBay. I'm considering getting a japan colour FE one also as they are apparently different. I was never previously into army building apart from one of each of the seekers, but the way the vehicons are presented in the show and the fact that there are different molds makes it very easy to justify getting as many variants as I can. (I'm not addicted, I can stop any time I want)
I am yet to actually open any of them so I have no real opinion, I do love the idea of army building different molds though. This is also why I am surprised and disappointed we never got three versions of the dreads from DOTM as deluxes.
Great pictorial review, btw Goki.
