I said in my initial post that people just needed to let me know what they wanted per insignia. They can ask for whatever ratio they like, I may or may not be willing to pay what you are looking for.
farming 140k credits is not too difficult, more importantly there is a credit cap of 3 million so at some point you are required to "burn" them.
I guess I don't really have a ratio in mind. I would be willing to pay more than 20 per...
But, I am also getting close to maxing my crafter at this point, so my timeframe is getting smaller. At any rate, thanks for the credit farming tips, and the ISO tips, I am still looking to pay for some Insignias if anyone wants to trade them.
