auction house.
a3/4 of hell is a decent place to farm i guess. get your valor stacks and roll the elites. regardless of what you do, essentially you're going after gold instead of items because that's the most efficient way to gear for inferno. if you happen to find gear for yourself in the process that's great too
once you get some gold, like i dunno, 500k+, just troll the AH for your slots. sit there and browse pages until you see the brand new auctions at low prices and hit the buyout button really fast
