I've heard that the chain parts stores will scan for free (not sure how valid this info is). I also seem to recall years ago that my local wheel and tire shop offered to do a scan for $90 (they ended up doing this for free as the mechanic apparently couldn't remember if the light was on prior to service). From my limited research I've found tools ranging from $50 to $250+. Just wanted to know how useful this tool would be and what features are "essential" and which are the bells and whistles.
*Disclaimer: This post is being made with expectations of comments related to poor forum seach skills on my behalf. I did find some info here, but nothing that placed a value on having a scan tool (maybe it's a no-brainer), or served as comparison of one vs. another.
Thanks in advance.
