I bought a used Toshiba 51H93, and it fell over in the back of my truck getting it home (dumb, I know). Fortunately, it still works fine, but the front screen has a crack in it. It looks like plain clear Plexiglas (Perspex for you Brits) so, as near as I can figure, the correct replacement part is called a "Screen Protector", and retails for about $45. Unfortunately nobody has it in stock, and the first vendor I tried to order it from said there'd be an additional $45-$100 shipping charge since it's oversized. Can I just go to Home Depot and a have a sheet of Plexiglas cut to the correct size, or is there something special about the correct part? Also I'm only about 90% sure that the Screen Protector is the correct part. I see a a "fresnel screen", and a "lenticular screen" on the parts lists, and they're about double the price of the "Protector". As I said it looks like plain clear plexi, and not some funky lens.
