Used rock is just that, used. It is likely plugged up with detritus, full of PO4 and just a problem waiting to happen. Unless you know the person and they're shutting down unexpectedly, and you know the rock is nearly new, I'd avoid buying somebody else's used rock. It's really not the area of a reef to scrimp on..
