When i played through the SP i trades even more and got myself the The Werewolf (i think) on a planet in NY system, at a price of 10mill the more price effective variant would be to have a look around the northernmost asteroid field in NY and keep an eye out for a Black Eagle (and mines:)). also having one shield buster type weapon is pretty helpful in this mod. and try to use guns of very similar speeds as the targeting computer only uses the fastest velocity to aim.
