i know plastic sounds awful, but you have to see these to realize they are
actually substantial. although never having bought one, I would be
interested to hear what people have to say about the plastic ones.

It might be worth looking at agricultural suppliers - you used to be
able to get 8' x 4' x ½" sheets of plastic 'chipbord' - very srong, very
waterproof, battleship grey, and can easily be cut with a panel saw,
bent, moulded, etc.
