Code Reading Tool

I couldn't find a place to post this question, so I'm posting it here. What are the best, reasonably priced code scanners/code resetting tools for our Pontiacs? There are always a lot of them on ebay, but which ones work the best?

There are a lot of tools out there. Actron makes reasonably priced code reading scanners and you can purchase them at most stores that sell tools. You can also get them at most autoparts stores and at Sears. If you really want an in depth tool you can't beat Autotap as it will do a lot more than a code scanner but expect to pay around $300 for the program as it works with your laptop computer.
