GreatPlanes Building Board
 

More of a warning than a review. I purchased one of the Great Planes Building Boards from a local hobby shop. It began to warp and bow in about three days after removing from the wrapping. I had it laying flat on my work bench. These are made from laminated balsa and take pins very well but obviously I am dissapointed. It is still useable after mounting it on a 3/4 plywood base but I hoped for better results. I probably would not spend another $24.00 on another.
