It looks like it may be a female to me, so if there is someone, with a male near you, you may actually get a buyer, for what you are asking.
But I agree with Jonclark, unless there are people in your area with monster cichlid tanks, that species may be hard to give away, because of its needs, and volatility.
I picked up a similar sized female in Chicago a few years back for $25, because I had a male, that had already killed off 3 females. My males rep for killing females, made spending more, a gamble I wasn't going to spend much on.
I believe the seller had, had it in the classifieds for many months for $50 before I came along, and offered the $25. (he included 3 Synodintus it was housed with for free)
