I just searched for things I needed between MF games or every hour or so playing. I found my bow for 145k on the AH before the IAS nerf. Even then it was good, now it's pretty awesome.
Btw I'm not sure what post you think I was responding to. If you were the one posting the tank barb or some other endgame character this advice likely won't work.
Obviously going from great gear to endgame is a bigger leap and much harder to get a steal. Most of the time steals happen when you search a specific set of stats you desire, not an obviously beast item with 6 stats that are all among the best.
Then MF in late hell if you're having trouble. You can get up to ilvl62 in hell... outside of your wep, you can basically get gfg gear before you even hit inferno.
