I've only ever played Morrowind straight vanilla until very recently. So these Dark Brotherhood thugs want to kill me, huh? I went to Mournhold and made their organization my cash cow. I've killed nearly a hundred of these assassins now, selling their armor and weapons to local Mournhold smiths, over and over, to the tune of tens of thousands of septims. My favorites: boots $500, cuirass $1000, pauldrons $500, poisoned glass daggers $4100, daedric tantos $14000?. Most of this money, by the way, goes toward training.
