Bought mine on www.razorgator.com, I paid a lot, but since I've got a free place to stay, and a free flight, it didn't hurt too much. Went with them because they are reputable, and have sold tickets to previous World Cups. With that said, my wife found a site selling tickets for roughly the same as Razorgator, but they say they will garentee the tickets, if your not let in due to your ID and ticket ID not matching. If I can find out the name I'll pass it on.
