You get your 1st ship of each tier for free. Just throw stuff that looks valuable on market, vendor the rest. As long as you dont go crazy buying off player market you will have plenty of cash. By the end of Open I had enough to buy every ship in game with over 1.5m left, besides buying from player market money is not widely neeeded atm.
sadly it seem they nerfed the loot tables by a lot, in open i was rolling in money, and i am sure that was not ment but now i barly get any loot and its mostly crap so i guess loot farming is out till latter in the game heh
