All plus tax and assuming no setup. Setup is usually $25.00 – $50.00.

Naturally,
the nicer and more longer term the boards are the higher the price. MDO
is an actual ½ “ board, gives dimension like existing ones. Alupanel is
thin like foam cor but a very durable metal clad, doesn’t warp and bow
as much. I believe foam cor laminated is the stiffer and tougher version
of the original foam cor, think tempered – which it isn’t. Foam cor
original, handle with care and do not body slam it.
