Stone Library

Can anybody suggest a good residential stone library? I have the ArrowWay library, which is good, but I am looking for a library with a nice displacement map that goes with it.

The arroway bumps can be used as disp maps but they need a little love in PS. just some blurring and levels can work well.

I have tried to work them in PS, but for the money, you would think they were shipped with nice ones. Their gravel texture library has them, and they are awesome!
