For an easier place than outer terminus, I found the Grineer mobile defense mission on Sedna to be quite effective at spawning seekers. I got Shimmering Blight on my first run with ought a Nekros, and went back with a Nekros and got Shimmering Blight and Crushing Ruin. I admit, I probably got really lucky, but that's the best mission I've found for it so far. (Sorry I can't remember the name :p )
