WHere can I buy Manny Pacquiao memorabilia?

I am not fond of boxing but dammit Manny Pacman is just awesome. I first heard of him through my MOM, (how lame is that) who is a Philippines native,who was telling me how he i like Michael Jordan over there. I want to buy something signed by him but can you really trust ANYTHING on e-bay when it comes to this type of thing. My Steve Young, Jerry Rice, Dwight Howard,Tim DUncan, Manning Brothers, Barry Bonds and Patrick Willis memorabilia came straight from official team websites.Can't find anything like that for this boxer and even the ebay photos with certified cards look fake. Where do I go for something like this? PLEASE HELP!!!!!!
