Neal,
Great deal you found on Prime! I have to ask, do his legs retract properly when transforming into cab mode? I've yet to open mine, because I really don't want him - but if his legs work, then that may be a different story. I still think the voice actor for Prime on the base is god awful. Laughable even - sounds nothing like Peter Cullen.
DVD pack with Megs vs. Optimus. Haven't opened it. Still in my trunk with all my other Classics stuff. What DVD is included with this set? I can't recall a cartoon series where Megatron was a tank and Prime was his original g1 self.
