I have heard of folks buying large sheets of styrene(4x8) like you would building materials, and saving quite a bit. After searching the local metropolitan area(Philadelphia/Wilmington,DE), I came up empty. A friend is a tool and die maker, and at his job they use high impact poly styrene(HIPS). I am looking for product similar to what Evergreen Scale Models sells. Is there another name for it other than just “styrene”? Thanks in advance for any assistance.
