The one LFS here used to setup JBJ nano cubes with live rock, fish corals etc etc, and have em lined up on a counter. Their prices were anywhere from $500 up to $900+ for a JBJ DX 12 gal cube already setup, cycled and ready to go to their new home. As nice a some of them were it was still a package deal and aquascape etc etc were what they decided to do. They would change out fish etc, but that was about all they would change out. I have seen complete 12 gal deluxe cubes folks had setup and fully stocked sell for $250 to 500 already on various forums.
