Has anyone purchased this product??? I am looking for something similar to the Dashhawk, but I want one that comes with the software and cable so I can also use my lap top. So far Auterra has been the only company that I have found that offers a handheld unit and the neccesary items to be able to use my laptop. It seems like a great product, originally I was debating between a Dashhawk from MSD and Bully Dog's Watchdog, but they dont seem to be as useful as Auterra's DashDyno SPD. Any opinions?????????
