Nice. The directional light really adds a lot to the picture.
So were you on one of the guided tours? We're going to be making a road trip out that way this summer, and are considered Monument Valley as one of the stops but I heard the access wasn't very good for photographers (can't get to many points of interest during the "good light").
It looks to me like the expensive one was well worth it, this is an awsome shot as are the others that you have posted.
Great shot Mike.
I just love that lighting, it brings out the textures so perfectly.
