Bro just get Archeology, Artifice and treasure hunting. Buy the stuff for your droid. Seriously, remember you will always be able to BUY stuff. So make your Jedi self sufficient and save all your credits to upgrade your bot. I'm going to be a jedi that will be a self-sufficient biochemist, Why? Because i will make so much credit selling healing "potions" that ill be able to buy my sabers, etc and then some. You see if you make armor, it is not perishable so there might not be as much a need later on. But people will always need heal "potions" and they will use them up and need to buy more which = $Caching$ money in my pocket.
