For Bryce's benifit - Kein raises an excellent point. If you aren't certain of the tanks history, there is always a risk. I personally wouldn't buy a used tank without knowing who the owner was and trusting that they know better than to use copper.

If you are going to buy used, focus on tanks that have corals and inverts in them now, or otherwise do some digging around the previous owner. Impulse buys will get you no where in this hobby.

A general rule of thumb - the tanks the cheapest part in this hobby.
