Mine arrived yesterday from RK and I haven't stopped flying him yet. It's a VAST improvement over the jet version, and the colour apps in robot mode make him stand out from the uber expensive Japanese version (buy a whole box set).
The Megatronus is repainted differently to the prime master retail version - I quite like it, but will probably just stick him in the SDCC box set so I make up the twelve.
The packaging though.... its sweet. If you're on the fence, have a look at a YouTube video. Yes 60 for a deluxe is a lot, but I'm glad I have mine.
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
