What's a good place to farm for equipment that will let me attempt inferno act 1? I was hoping I'd be able to farm in act one but it doesn't look like that's going to be possible yet. I'm thinking either act 3 or 4 in hell, but I'm not sure if I should just like run through the entire act, focus on specific boss runs, or just kill champions/elites onry. I'm a barb if it matters.
