The foam is awesome. I call it extruded styrofoam. Known as styrofoam insulation board construction grade. Cost about $17.00 USD for a 4' X 8' sheet that is 2" thick. Home Depot, Menards, 84 Lumber, any large lumberyard.

The lumberyard in my area calls it "Dow board", price depends on what thickness you get. The one Johnny quoted sounds about right. My local HD only sells the pink stuff, the lumberyard sells both pink and blue - I prefer blue since I can use it as a blue sky backdrop without having to paint it right away.

If you're going to use foam, be sure to have some decent tools to cut/shape it with. Here's a link to a company that sells hot knives:

I'm sure you'll enjoy using it alot, I know I did!
