iamman,
Thought this would catch your fancey! Here's a link to get you started with lots of information, links, and plans for EPP planes:

I bought my 9mm - 1.3# EPP from rcfoam.com. It is $30+shipping for 6 sheets. The carbon rods were purchased from my local hobby shop. The thickness and weight of the foam and sizes of carbon fiber needed will vary depending on which plane you choose to build. I actually took my measurements right from one of the planes in the video and then marked it out on the foam. I then made a few modifications when cutting it out to suit my flying style (basically larger control surfaces all around).
The basic tools you'll need: Hot Glue Gun and hot glue (I just bought a cheap one from Walmart), Exacto Knife with lots of razor blades as the foam dulls the blades quickly, 3 foot ruler/straight edge for cutting and measuring, A right angle to make everything square, and Tempra or Acrylic paint.
