I'd say you got a great deal, considering it looks to be pretty much brand new, cheaper than the original cost of the bundle with the extras.
I just thought I'd point out a flaw in the seller's description for you though;
"This system is being sold with original games, movies, documentation and box that was included at the time of purchase."
Yet he clearly asks you to choose one game out of a list, including Ratchet and Clank, the game included in the bundle. He said that it's being sold with the "Original games included at the time of purchase", which means that one, so you -should- be getting two games.
I suggest contacting the seller about this and seeing if you can snag another game due to his inconsistency.
