i think there needs ot be a distinction about "locals"
"local manufacture": usually speedbombs or speed/k bombs, some can be good if that is what you are after, in my experience i haven't found a locally produced pill that contained MDXX, that is not to say that they do not exist though.
"local press": if the pill contains MDXX and is a local press, then it is most likely from imported powder.
there are 2 main presses of high quality MDXX pills going around at the moment, the ?/Chanel/ying yang etc press, and the lightning bolt/JA/butterfly etc presses.
there are others out there with a different press and still good quality like the clovers in sydney or the BB's everywhere...
i think that the ?'s and their derivatives are pressed here from imported powder, but that is pure speculation...
