Here's a couple of pics of a bait tank that Jerald (Catfish Quiver) and I recently bought, I think it was a steal really, $150. It's 7' long 30" wide and about 2" deep, has four screen dividers and a screened filter section,and a seperate section for hanging an agitator, which we have. It's made of fiberglass and is in very good shape. Not only the tank was included in the price, we got 45+ perch and goldfish, (large) and 35+ crawdads (small to large). We'd been using a stock tank, this'll be a lot handier. Similar ones I checked out on line were going for $800/900 bucks. The purpose of the board and weights on top is to hold down the base inside the bottom of the tank which was slightly warped from being outside the tank. Once it reforms to the bottom, we'll be able to take the weights off.
