Blueprints - Pricing (money) makes NO sense

The 20-stacker cost $125,000, while the Precise Cannon costs double, $250,000. The 20-stacker is the most capable blueprint in that it can stack 20 sand in one shot at long range, effective against bases with multiple water/lava walls that are up to 20 blocks tall (can be used for taller too), while the Precise Cannon is much less effective against such bases, only stacking 1 sand per shot, more useful for raiding underground bases at long range.
