There a reason I've been staying in and around Tepertsi for three years now. Systems here never seem to be in anything other than Boom and Civil War. Boom: imperial slave missions are a dime a dozen and pay very well. Civil War--weapons become the fun things factions want to move, and they also pay well.
Occasionally they dry up for a week or two, but generally it's been pretty solid for some time.
Quite a few areas like that, the region surrounding I-Bootis, Maia, Shinrata.. Even Sol. Although Pleiades is my go to area.
