The best sales are for new tanks 55 gallons and under. Those go for $1 per 1 gallon... couple of notes, those go one sale a few times a year and look into the Aqeuon brand of tanks.
Craigslist is your next best best for good tank. I picked up a very good condition 90 gallon with stand for $100. Keep looking as they go fast and don't be tempted by the stuff they throw in (fish, filters, lights, etc)
