Stay away from yonex rackets from ebay, now I know there are some sellers that sell authentic rackets, but it's best to just buy from authorized retailers in your area
How much is an authentic Yonex MP-99 at your local store... ??? I can only say that the person selling it either got the racket as a present and that he didn't like it and DESPARATELY wanted to get rid of it, OR, he's giving you a present. Possibilities of the above are there, but slim. So what's the 3rd possibility?... Well done man.
