Tom, I LOVE your signature buddy!!! I would go with Toms sump, or build your own out of a small tank. You can get your local hardware store to cut you some plexiglass and you can stack CD cases to support, and shim the pieces while you silicon them to the sides. That way you can customize it more, and it saves you money. Also if you do it this way, you could make a larger one if it would fit under the tank.
