You can buy polarizing material in sheets at any good theatrical equipment store that sells lighting gels. They're about 2x3 feet and most are in the $5 US range, at least in Omaha, NE where I last bought a few. Glass filters are another matter and very pricey. B&H lists a Linhof 105mm Top (Linear) Polarizer Glass Filter $603.95 and a B+W 122mm Kaesemann Circular Polarizer Glass Filter for $574.95. They also list a B+W 4x5.65" Circular Polarizer Glass Filter for $488.95. Go to http://www02.bhphotovideo.com/default.sph/FrameWork.class?FNC=CatalogActivator__Acatalog_html___CatID=4038___SID=F0137F72400 (make sure you copy the entire address), type "polarizer" in the search window and you'll get over ten pages listing 250 different polarizing filter choices from most expensive to cheapest.
