The problem is there's an AH and botting has become big business now. Definitely don't expect to find an item that'll be worth millions, because I've been playing for 450 hours on my monk, since release, and if you don't have the MF to reach the top tier items, you're just playing catchup. I've been playing catchup the entire time and rarely find an item worth more than 1m.
Don't play for the lottery. Play for the enjoyment of playing. If you're looking to upgrade a few DPS here and there, then screw the AH. It'll just make you depressed. FFS I know I am everytime I try to tweak a few DPS higher. But I still enjoy playing. So I try to keep it simple like that and not try to get caught up in the DPS race and competition. My monk can sufficiently kill on MP5/6 solo anyways, and that's pretty cool to me.
