I want to purchase an OBDII scanner for my 2006 LBZ. I just don't like spending $100.00 every time I have to go to the dealers to get the reading and then be able to fix the problem myself. I would like one that is self contained with an LED readout but I don't want to spend $Hundreds on one if I can get one that works good for a couple $hundred. What do you have and would you buy a different one now that you have used yours and why?
