I recently purchased one of these off of Ebay with a DVR docking station. I am planning on taking JPEGs of upcoming opponents defense and bring this out to pratice with me so I don't have to carry a number of scout papers with me. Additionally, it will allow me to start keeping a digital archive of how different defenses align to our offense. I picked this unit with the DVR for about 150 dollars. I let you know how it works in the near future.
