You can get polystyrene at any hardware store, builders ware or Hobby shops .
I do have a site of a company that sells Polystyrene to the public and bulk aswell thats alot cheaper I just can rember where I put the info ..

Ja I have It also works pretty well, apart from me breaking the trigger of the can and haven to make a hole in the tin to get the foam out. Needless to say pressure and expanding foam does not work well togther with a puncture hole. It was the messes project I have done and ended up throwing it away .
But it does work and you can use it to stick Polystyrene and stuff like that together It makes a really nice design tool to any project.
