If it's controlled, it's not a "drone". Drones are preprogrammed prior to launch, with no alterations to the mission possible once launch has occurred.
RPVs are controlled.
Both are subsets of the UAV species.
As for EITS' cost question, I don't know, but Sperwer was the most expensive aircraft in the CF during its day, when all costs were included.
We would still have to pay for a crew, plus expensive ground control systems and, for longer-range missions, satellite control systems, and the only gain for that would be endurance.
There were several times, during my Sperwer tour, when we were the only ISAF aircraft flying in Kandahar Province. The bigger and fancier UAVs could not operate as low as we could, and could not see through cloud layers that we flew under. The same was generally true of manned aircraft. Weather conditions sometimes precluded helicopter operations as well, but we would be up.
