Back in my first couple years of playing this game, I did a sorta round-about way of acquiring specific Faction / Deadspace modules that I normally couldn’t gain myself due to location, lack of skill and or equipment.
At that time Gistii 1MN Afterburners and Microwarpdrives were hot items to sell so I started running low level Angel exploration sites which mainly dropped those modules along with Domination mods every once in a while. I ran those sites quite regularly for a couple of weeks and quickly built up a sizable amount of those prop mods for transport to a trade hub, sold them and then bought the specific Faction / Deadspace item I originally wanted.
In the process of doing that I was contacted by another player who offered to buy all the Faction / Deadspace prop mods I could get for his PvP Corpmates. Since I had a buyer set up I continued running those sites and every 3 or 4 days I’d contract him about a dozen of those modules.
Needless to say it was very profitable and after a couple of months of doing that I started looking at other ways to make more profit. For some reason at that time Dark Blood Power Diagnostic Systems were almost triple the price of True Sansha Power Diagnostic Systems yet they both had the same stats. So I started buying all the True Sansha Power Diagnostic Systems that were for sale in public contracts.
For a month I continuously bought and hoarded those modules with the plan to ‘Buy Low and Sell High’. After collecting over 2 dozen of them I started selling them at a price above the Dark Blood mods. Much to my surprise they actually sold very quickly, meanwhile I’d still buy the True Sansha Power Diagnostic Systems as soon as anybody placed them in the contracts at their original low price.
Needless to say I basically cornered the market on True Sansha Power Diagnostic Systems for about 3 months before others got wise and started matching my price. Course by then I had built up plenty of Loyalty Points by running missions for Thukker Mix to purchase Thukker Shield Extenders which was another hot item to sell.
During all that time I’d also buy other Faction / Deadspace mods that I needed but couldn’t actually acquire myself in order to bling fit a couple of my ships to use for exploration. After a few months of selling Thukker Shield Extenders, I then began doing exploration extensively and soon after that I was able to start stockpiling various types of Faction / Deadspace mods. Today most of my ships are bling fit and even though my wallet only has a few bill ISK in it, I have a very large stockpile of Faction and Deadspace modules to work with and or sell if needed.
Now don’t get me wrong, I’m not saying those exact steps and items will accomplish the same results today. However the general premise of what I did is still sound and should basically achieve the same goal, you just have to do some research and see which items are hot, then start with the lower ones and work up to the higher ones. In the process of doing that you’ll be able to easily get the items you want.
