Well, if it works properly, I won't mind.
Would you spend more than double the price of a non-original gamepad for an original one? Is it worth it?
PS: That gamepad at the bottom of the picture on that page that has it's "rear" facing us seems to be like the one I had got with my 2nd hand SCPH-39006 console (I see a white sticker at that same spot on it).
I got it broken (The cable at the plug seems to have a poor connection, possibly because it was strained by it's previous owned), and the cable seems really much shorter than my original Sony DualShock 2.
