ORA only sells to retailers. You have to find one that uses them. However, Liveaquaria does.
Both are very good. However all urchins also love coralline algae, so they will eat that too, just an fyi. I find tuxedos tend to carry more frags than the varigated although varigated are larger. I like the varigated because they are captive bred too. Mine even spawed in my system. I never found babies though.

. I had coarline algae taking off a few months back, but one day it just stopped and died I guess. Corals probably using all the Kalk, so them eating coarline isn't a problem
