I am MAD...I paid 120 for a 55g with filter, powerhead, heater, hood, gravel, and stand (which isn't bad, but come on $31?!?!?!?!)
A buddy of mine bought a 90, stand, sponge filter, hang on filter, gravel, heater for $100 from a local guy that used to breed cichlids (he is using it for freshwater), but it leaked when he filled it up in his classroom. He sealed it himself and has been working perfectly for about 3 months now (it wasn't all that hard to do).
