I imagine I could make about six of these in about 15 minutes, and at a cost of around $20 ($8 for the screen +$12-$14 for two pounds of live rock rubble, 1000-2000 pods
depending on various sites and various sale prices run around $45 shipped. It may be worth it I don't know have not done it yet. I don't dont really look at it as work, I don't like a "set it and forget it" tank, I'm always tinkering, the result for me is just about secondary to the process. If my tank completely maintenance free I would soon loose interest.
