If it were Abominus or Predaking done with some minor deco changes, I'd go for it (from the cheaper foreign option), because Abominus never got the boxset treatment and I want a second set of Predacons to have one in combined mode... but the Combiner Dinobots is just something I don't have an attachment to, because it was never a concept in the original era of stories, or ever really (if they did in a more recent story setting, I'm drawing a blank on it).

If I'm not mistaken, the Power Core Combiner "Dinobot" set was probably the closest we had to a combiner Dinobot toy team in the 36 years of Transformers?
