It doesn't take too much gear to get into, the key is survival so even if you do 10000 dps, as long as you live you are winning. From there you want to increase your dps and try to get MF on each piece of gear you have. Depending which bot program you use there are plugins that can make it a lot easier (such as auto-sorting gear, auto-salvaging/vendoring).
Note: DPS can be considered a survival stat... the faster they die the less incoming damage you take.
This takes more work, but is a lot less risk and higher potential reward.
- More work because you have to actually sort through the items that aren't automatically salvaged for being bad, then you have to post and sell on the RMAH/Gold AH/Trade Forums.
- Lower Risk because profiles are A) Longer, B) Naturally "randomized" and C) you are dealing with more than just high amount of gold.
- Higher potential reward because, while you always get a pretty steady amount there is the chance you can get a super premo item that sells for a ton. This is also true for GPH profiles, but farming champions has a MUCH higher chance.
