Sorry for my ignorance, but what is a pcb diy?
As for multilayer - I do this, meanwhile on a regular basis. The main
thing you need is a through plating station. Once you figure out the
process and provided you get the FR4 material in thin enough sheets (I
got mine from Bungard) it's not that diffcult. To give you an idea, to
create a four layer PCB it takes ~5 hours. That's however (still)
without CNC drill (which would cut the time by ~40 minutes) and no
solder stop mask and thining aplied. The latter would add another 30
minutes. However I usually only need prototypes that don't have to
look goog but meet the physical dimensions (and must be working of
course) of the final product.
