Sump help?

[mandyplo]

I am doing a big tank move in the next week!!! The tank is coming from my boyfriends house to mine, because well.... if you saw the current state of my tank (my baby) you would confiscate it as well.

So I've decided to add a sump, my tank is only 55g, its my first stab at a marine system.

I had a fellow in my home town who sells coral/fish/equipment out of his home, and he was going to order me a pre-made sump for a decent price ($285) with overflow box and piping, and all of a sudden he has jacked the price way up on me ($450!!!!)

So my question: is there somewhere online I can find a set like this, sump overflow box, pipe/tubing, return pump...?
Or any website at all where I can just find a sump already sectioned off and everything? Any sumps you guys would recommend to me?

Oh and did I mention I also don't have a local fish store where I live... >.> small town....
