You can pick up a tech ii scanner clone for about $350 from China. I have one and I use it all the time. It has proven to be rock solid reliable and does everything a real one does. Mine came with a USB key that will authorize changes to your car. If your VIN is not in the key you get then for a small fee you can get authorization just like any shop doing the work for you has to do.
