I found this spot that can be farmed without the best gear in the world. Although I think running something like Siegebreaker is probably over all better, that is just something I can't handle and I'm sure some other people can't really do it yet either. This place I have been using has paid off pretty well. I'm sure I'm not the first one but I haven't found much on it and I've had it to myself long enough. Its pretty cheap and unfortunately like most stuff in this game its not really Melee friendly.
You start in act 3 Inferno on either the very last quest "Kill Azmodan" or "the second heart"
Enter and go to the waypoint "Tower of the Cursed Level 1" (Make sure not "Tower of the Damned")
Now you can either run through level 1 if you are skilled enough or just kill your way through. Whatever you have to do. It can be tough sometimes.
Eventually you'll get to "Tower of the Cursed level 2". Here is where the fun begins.
There are Ledges on both sides of the starting platform (The one on the right is actually over the edge of the stairs) and what you want to do is pull elite and champion mob packs to the bottom of those ledges and just let them kill you. You will respawn right back at the top of the stairs and you can safely blast them from above. Sometimes you'll even get lucky and the Elite/champs will spawn at the bottom of the ledges and you wont have to drag them anywhere. Right before the kill shot put on Magic Find gear and let it rain Act3/4 Quality rares.
Here is a video I made of the run.
A few things to not that I didn't explain in the video and its causing a lot of hell in the comments....
1. When you leave the game and resume the game sometimes it will put you in town instead of on level 2. To fix this all you have to do it leave the game from town and resume and it should put you in the right place. If it doesn't then just leave and resume again. Eventually it will put you in that tower as long as you didn't get another check point.
2. Tower of the Cursed. (People keep going in damned)
3. No my gear is not 10 million gold worth of gear. I got my bow for 350k and everything else is like 50k or less. Anyone with a ranged class can do this. You will die. I Die. It doesn't matter you will still make money or get gear. I promise.
4. The run through Tower of the Cursed level 1 can be a huge bitch. Sometimes its super easy and sometimes its a huge pain in the ass. Once you get to the right zone it shouldn't matter any more.
5. The last thing I didn't mention that makes people cry "this got nerfed already" or "fixed" or whatever else people are spamming on the comments is sometimes when you reach Tower of the Cursed level 2 it will be an alternate zone. There are two different zones you can get when you go in and the other one is garbage. If you don't get the zone with the Harpies off the edge of the stairs immediately to the right then it's the wrong zone. Restart.
This place works for me I've got a ton of gear upgrades here and made well over 20 million gold (I spend it all on my Wizard not my Demon Hunter) I'm sure this place will be useless when the update comes out that makes ilvl63 gear drop in act 1 and 2 but for now its great. Just make sure you get those kill shots in full MF gear!
