The specified aluminum/polyethylene/aluminum sandwich (Dibond, Alupanel etc) is an excellent material -- can't improve much on it. It's lightweight, very stiff, available in a range of colors ready-finished and covered with a tough coat, commonly available, not flammable, fairly cheap, there are plenty of companies with equipment to cut it to your specification, and cutting is not terribly expensive either. Most sign makers will stock it and cut it for you. What's there not to like about it?
