Best source I've found is at any pilot shop. Go introduce yourself at the nearest one, tell them you will haul away their outdated approach books for free so you can use them for sim-flying, and would they mind setting a few aside when they're updating...
I am building quite a collection... some VFR charts and IFR enroute charts, too... all unused, and free!!;D
