Really hard to find now, was 18.99 a lb last time I saw. Vanuatu rock was nice too, also hard to get now.Assuming you can find it, I don't think you can beat pukani even if dry in terms of porosity and structure. I used Caribsea Liferock shapes for my last build (barebottom) and I am at the one year mark and have still not been able to get SPS to grow in the tank. The tank just hasn't come into balance. I just set up another tank using pukani (from a LFS sump) and sand to make sure it wasn't my husbandry or something else, and instant success.
I will say I did not have the same experience that others have with coralline not growing on the Liferock. Mine is completely covered in coralline after a year. It looks nice and is easy to work with, but I would never use it again.
