I've been trying to find a looting filter system, so I can still auto loot, but not acquire grays.  I checked out these guys, but the interface was confusing and not worth my fear of the comments on the page about it auto selling and deleting.  Does anyone have or know of a good addon that can filter out what you loot, maybe even place items in specific bags as a bonus to it?

Dunno about a loot filtering addon but i know that selling grey items doesnt empty my pockets at the end of a failed naxx raid.

im using this and its realy good
