Yeah, that is an idea. Buy the whole set-up, and then whatever you do not use, sell it to other fellow reefers on the boards here. Then, everyone wins. The guy sells his stuff quickly and for the price he wants, you get a awesome deal, and the members of this board get a lot of great-priced stuff. The only items you could not sell here are the tank, stand, refuge, sump, etc. unless it was local pick-up (since it would be impossible to ship anywhere). However, you could make $600 of your money back on rock if you charge $3 per pound of rock. You could sell that rock in a matter of days if you unloaded it at $3 per pound. You could probably get at least another $500 for the lights and reactor, which would leave you with the tank, stand, sump, fuge, other fish for $400. You could unload the tank to someone for $150 just to get rid of it, and tell them that you will throw in the stand and filter for another $150. That leaves you paying $100 for the corals that would easily have cost at least $1000, if not WAY more, depending on what he has.
Plus, you get the satisfaction of knowing that everyone is happy with the transaction.
