I just got my setup minus rock and sand for $250 - see the link in my sig for pics and such - it even has pc and actinic lights and came with hydrometer, 640 gph Rio Seio powerhead, biowheel (which I'm not using), full original custom mechanical filtration (not using also), marine test kit, nets, etc - I had to buy salt, got another 820 gph seio (plan on doing reef) and LR/sand. Not a bad deal!
Craigslist rocks!
