Depends. About 2x which is fair given the you've double the # of layers.
A $20 board would now cost $40. The signal integrity of boards with
integral ground planes is much better and so is routing.
I never look at that end of the segment where I work. Most of our boards
are about 500mm x 600mm, have 22-28 layers, buried vias, buried caps, etc.
The 1-3 piece price will buy you a nice car.

I'd like to complement him on the writeup on his site. Really a great
read and excellent web content, diagrams, etc.
