Eagle makes fair and compelling arguments, but I would still absolutely urge you to wait the year or two and do Africa. Given you're on a budget, I can make no higher recommendation than Touch Africa Safaris, Zimbabwe. I hunted with them in 2010 and it will be the experience you're after, no question, and presently a Cape Buffalo hunt can be booked for $9,000. The Cape Buffalo is substantially more dangerous than the Asiatic Buffalo, there is zero question on that, watch the plethora of Cape Buffalo killing Lion videos. They are a true beast, and likely kill more hunters and PHs than any other commonly hunted animal. That is still a very small percentage, but they are true dangerous game and demand enormous respect. There's something very special in that.
