Hey Steve,
Ya need to play the auction to get a good deal. The one I saw for 5 ft3 came to 12.00/ft3 including shipping. That auction ended.

If you bid 5.00 on the 2 ft3 auction and win (which you probably will) shipping is only 13.90. So that comes to 9.45 per ft3 delivered. Then you wait till they list more.

Aquatic Eco Systems sells it for 49.00/ft3.

You can also make it yourself if you have access to a lathe, although it sure is a PITA.
