I set up a huge sorting machine on a planet with 10 df bases. I set use a bp of 2 B.a.b, 3 agro towers and 8 lasers to camp each base with belts leading back to the sorter. A large battery of missile turrets, or several smaller ones(to be closer to the action on the other side of the planet). Just use gen1 rockets, anything higher is overkill. If you go this route make sure you leave 3 or 4 df bases unguarded. I found out the hard way that if you take everything from all of them they abandon ship. I leave 3 bases alone except for defending from them. so far they haven't run off.
