Ya, what he said. "Let Juni wait." The Single player game is designed to give you just enough cash to continue on. Sometimes it's barely enough. When she calls for your aid, or to meet you somewhere, take your time. Grab a few more missions. Better yet, grab a freighter and do some trade runs then buy fighter and go see her with your pockets full of gold. They say size doesn't matter, but we all know Juni would prefer your wallet to be bulging at the seams. Just avoid the places she wants to meet you until your comfortable with the amount of money you have.
I know I'm mad late, but this is what I did to start out:
I finished escorting the convoy and I bought a shield buster for the third hardpoint on pitssburgh and set out to finish the mission. The I took missions on pitssburgh and got enough for a rhino. I loaded it out whith 2 shield busters and kept turning them on and off in order to not waste energy after I was done with the NPC shields. The five justice turrets would take out the NPC in about 5 secs when he was comming head on after he turned. I got money real easy and new zaphiel turrets that I tractored in.
Please correct me if I'm wrong.
