I wouldn't really classify it as a monster but my 55 i got for AUD$250 second hand. Came with tank/lids, cabinet, hood with built in light (which I don't use- I prefer open top), a decent sized external canister filter and a few small things which I didn't end up using. They had a foot long pleco and a 4 inch clown loach which the guy couldn't get rid of. Traded them in at a local aquarium store for around $180 store credit, which I used to get the driftwood, plants and some of the fish for the new setup. Just bought Flourite, T5 lights and sand from various other places and eventually put it all together. I now have my eyes on a much larger 8x3x2 foot tank.... Now that will be interesting to transport.
