Emso scampers off to find what you need.
It takes awhile (and several times you are tempted to just use your lightsaber) but eventually you have the old unit out! It is just as heavy as the other, so you will need the loader droid to actually pull it from the ship. It is separated at least, and disconnected from any wiring.
Emso returns to report that the Temple appears not to have what you are looking for.
"That first one would be a pretty abusive use of my powers and this is far too trivial to be bugging the Council about," Wentar says, shaking his head. "I'm unsure, if they've got nothing to do, maybe."
I'm wondering if there's a way I can just order a droid and just have them charge the Jedi Order for it.
As the prequels show, the Jedi are fond of airspeeders for flitting around Coruscant. Being a talented pilot, Wentar can snag one easily for himself, something than can bring back a loader droid.
You fly out to the marketplace you pinpointed and land. The droid warehouse is a short walk from the landing pad.
The droid warehouse is nestled into the side of one of Coruscant's multitude of skyscrapers. This is closer to the surface, so sunlight still reaches the platforms that you cross to reach your destination.
A grouping of droids are displayed in front of the warehouse, of all kinds. Most of them look used.
