It has been pointed out that there is an inconsistency in Teleporters.
While rare mineral requirement drops with higher levels of technology, so too does the production requirement. As such, even with the drop in blueprint output, there is little no point in researching and building the lower mks and mkIII is completely redundant.

When the other changes come in the Teleporter will also be altered.
Mineral requirements will remain the same as will mass.
Production requirements will increase mkI=40, mkII=60, mkIII=80, mkIV=100
As with other items where the production requirements increase with mk, all blueprint outputs will be set to 1000.

The result is that advances in production will compensate for rare minerals, which is as it should be.
