LF: Aquarium to use as frag tank

[Goomba]

Looking for an aquarium that approximately fills the following needs:

-around 3 ft long (greater than 2, but less than 4)
-drilled/cut for overflow of some kind
-around 20" high
-around 18" wide
-no copper medications used in it, I'm using it for coral
-rectangular shape, no bow fronts or diamond corners
-I have a sump already, but will take one if you just want it gone
-cheap, I'm just looking around for a dirty ol' tank that's been sitting in your basement. I don't want a nice start up kit or anything like that

Thanks for having a look
