Alternative for Gaming Mats

So recently I came across a company named Banners on the Cheap.  Basically, they make those giant, vinyl, sale banners that people put out in front of their stores for you to see.  I saw here that someone had used them though to print out a battle mat.  Being the resourceful sort, especially since their prices are much lower then Chessex, I figured I would give it a try and see if I could acquire a battle mat for cheap.
