Soon the first Transports will be in dire need of protection, the Imperials are already plotting and scheming
What lists are you thinking of fielding to ensure the Rebellion will live to fight another day?
In my mind there are two ways to go with the transport. Load it up and put it in command of the battle, or keep it empty and dump 270 points in the escorts.
Fully loaded with what we know now, the transport will cost about 60 points.
