Hilly Land in East Texas?

I'm looking for land in East Texas near Northwest Houston. This isn't for ag usage but just for pleasure. I am looking for hills and rolling land as much as possible and realize that this isn't much of a possibility in my location. To give you and idea of my expectations Navasota has some decent land with nice hilly terrain, but it's quite expensive. Anyone know about simmilar land but at lower prices? Town names or road intersections will be appreciated, but not entire counties. Even grimes county has ugly and beautiful land.
