im going to go the opposite route and say that buying a used set up can save huge cash if you look for the right one, ive moved probably a dozen setups and even one a 12hr trip in winter and ive lost nothing but a few fish and some corals and alot of them ive lost nothing.
that set up is def not worth 3000 but there are some good ones for alot less i personally wouldnt pay more than a 1000 for that particular set up.
buyiing all new is costly so if your starting fresh try to buy secondhand or lightly used equipment.
my lights alone for my tank cost more than what i paid for the whole set up and i lost nothing in the transfer and waited for a healthy good deal.....
cheers
