I think I'll stick with perlite for now. Much more reasonable.
Perlite is fine. Try to get the perlite with large pieces. Sometimes the bag is small pieces and is not as good! I use small lava rock also. It works well too. Pumice is hard to get and getting harder! Our club had a great source for pumice, but it was on American Indian ceremonial land and we can no longer get it there.
