I've seen most of these sold at PROP auctions if you can wait. I'm sure people will bring stuff to the FRAG meeting too. Reef Culture has a few in their main display and if you ask they might give you a fresh cut. Aquarius had a few of those pieces last weekend. Ask Carlos about the "Carflo," which is his efflo -- looks nicer than most $500 efflos if you ask me.
$500 efflo and the PM aren't easy to find but I'm sure someone local has them.
