Assuming all other considerations being equal (size, # of holes, hole sizes,
etc.), what is the typical cost adder for going 4-layer from 2-layer?  1.5X,
2X. etc?

Also, in an EMI-sensitive environment, how would you recommend the layer
stack-up?  Signal 1, Ground, Supply, Signal 2  OR Ground, S1, S2, Supply?  OR
something else?

Thanks.
