Well, i understand that glass would be the best way to go, but it's expensive! It's going to be adults playing my game, so i don't think i'll have to worry about scratching too much, no one will be very rough with it. I just want to make sure it won't distort the picture...sometimes i've seen it give off a rainbow tinge to the light.
How much did it cost for your glass including cutting...i need about a 24x24 inch square.
