I've been using those crap plastic expanding drywall anchors for years. Usually they work fine for a year or two, but bump whatever they're holding in or put any weight on it and they rip right out of the sheetrock. I was at the local hardware store and noticed these things called Sharkies. They look just like the crap plastic anchors, but they pop open on the other side of the drywall and really hold in place.
I tried a couple on a shelf that was being held in just by the tension of the anchor and they are freaking awesome. A pack of like 8 was $1.50 and there were a few different sizes.

. One evening we heard a loud crash from the bedroom and discovered carnage. I put it back together with some new parts and these anchors. It's still overloaded, but it's holding.
