I'm sorry that my response wasn't helpful. We can only respond reasonably based on the information given. Based on the information you gave and without making assumptions, I have to stick with my original statement.Eh. You wouldnt pay $100 for gsp would you? Especially sense gsp is common and even if you were "willing". But thanks for the response. I'm looking for the average price of this kind of hammer. Do you know it?
For example, where I am located, there is only one LFS that carries fish and rarely inverts. We cannot have corals imported. For me, if I wanted GSP and it was for sale at that LFS, I would certainly be more than willing to pay $100 for a reasonably sized colony as that would be the only source. The same goes for the hammer you were inquiring about. I'd actually be willing to pay much more for a reasonably healthy, single-head as this, again, would be the only source. Knowing my circumstances, skill level, system, etc. certainly helps in providing guidance in what I might or should be willing to pay for any coral. If my LFS sent me that photo you posted and said they are $100 a head, I'd gobble them all up. Context is everything.
