from what I can tell, a sheet of REAL 13-ply birch is about half the weight of MDF.

The home depot by me does, but not every store is the same.

With more layers, there is a more uniform density as the knots that you get will be for a smaller layer. I've also been told that the cheaper birch (ie. the "premium" birch at home depot vs real baltic birch) uses other types of wood, or lesser quality birch, for the inner and bottom layers. One side will have a nice look while the other side will look ghetto and not pretty.

yep, thats true, worked at home depot, their lumber selection was shit. We always were marking shit down because it was such bad quality, we always had som many complaints about the wood.
