Plexi glass

Anyone know where I can find a sheet of this stuff for fairly cheap.  Im looking at building a table that I can lay under while some skates, dances are whatever and take some wicked shots from a really cool angle.

let me know if you have a contact or may have a sheet laying around.

Prefer if you in or around Sydney

Just goto anywhere that works with the stuff and they should be able to give you some cut offs.  Though for the size that you can lay under might cost a bit.  Also so you know, plexi glass scratches really easily and can’t really be buffed out.  There is scratch resistant stuff but thats really expensive.
