Watch what you're digging up; this thread is well over a year old! Nevertheless, this particular sub-forum has seen a drought of activity as of late, so I suppose a little necromancy now and then could do little harm.

Anyway, getting back on topic (as old as the topic may be), my favorite money-making scheme--at least in EV:O--is the Thier-Gribn run, better known as the Miser's Funeral. Gets lots of cash, real quick, allowing me to outfit my ship with the upgrades I want, and get on with more exciting things, like conquering the whole of known space.
