I have a 40 gallon and a 5 gallon tank that make me very happy but would like to keep expanding (particularly to some more exotic marine animals) and have been looking into 150 gallons (180 gallon tank is the perfect size for the space i have set aside). Im going to be using $ i have left over from my beginning ($350) for this and so dont have a large margin for nice things. Ive only found good deals like this on craigslist. The four things ill need are the tank/stand/heater/light. The tank is my main concern then the light. I wont have nearly enough money left over for halide light

but figure ill get some high wattage power compacts. The heater and stand arent too big of a concern. As for filtration therell be
LR,
live sand, and a connection to the 40 gallon.
(read here if you dont want to read that large portion)
Basically i want to know if anyone knows of a good place to buy EXTREMELY CHEAP (total setup: tank/light/stand/heater for $350 at most).
