Much cheaper equipment and (uh... um.....) stuff.
FYI, aquariums like what Steve posted up aren't hard to achieve. I had a planted tank simliar (though not as pretty) running for awhile with 4x55watt pcs and a DIY co2 injection system with just a couple of fluval 404s for filtration. The pcs have since faded a bit since I started the tank, and I've taken my co2 injection offline. But important part was, no algae
