Take a look at what the above supplier has to offer. 4x8' sheets with 13mm core and face layups on both sides for $172/sheet (qty 1). The listing does not have the specification for the face laminate, but I know they are quite responsive to questions. They have panels with veneer on the surface too if one wants it to look like wood. This store is considerably cheaper than most other places that make panels.
