Benchwork: Why a hollow door? - Model Railroader Magazine

 Just checking prices ar Lowes, a brand new hollow door, plain, no holes drilled and NOT prehung, is about the same price as a sheet of plywood. Of course the plywood is bigger, but it's also much heavier. If you are building somethign permanent, it may not matter, but if you want something moveable, the lighter weight of the door will make a big difference.

 A used door, or even a new one that has been damaged, should go for a lot less than a sheet of plywood.
