Be that as it may, it all depends on the market. Would I pay 60 bucks for an frag I think is amazing? With no availability of coral around me the answer is simple, yes. Would someone who is living down somewhere near the ocean and there are several LFS to choose from with huge selections? Probably not. Do people who can attend frag swaps or other events? Probably depends on the rarity of the piece.
That said, do I think some prices are way out of control? Definitely. Hundreds of dollars for anything that we put in our tank is too much. If something is THAT rare, then it should be housed at an aquarium or museum for public viewing.
