I agree with others regarding ROTF not being the best investment. I buy spares of my favorite toys in case I break them 5-6 years later, then i don't have to worry about tracking down an expensive, vintage toy. I also really like the look of TFs in package, but that's pretty line-specific. Unfortunately, with ROTF, unlike its Universe and Animated predecessors, Hasbro didn't make the side-view display-worthy, which makes spacial demands more heavy.
This is not the case anymore, at least with ROTF.
