Yeah really the only way to get him now is to grab an Optimus/Magnus 2-pack from eBay or (less likely) try and get the Magnus/Skywarp pack from eBay. Both are fairly pricey options. I managed to get the Magnus/Skywarp pack from a seller in the US, total cost ended up being just over $70 but this was when the dollar was way up in the 90's.
