Autel MaxiScan MS300 Simple, cheap, and very effective..

I've only had this a few weeks, but I've already pulled several codes from my own vehicle (1998 Volvo S70-T5) and a couple coworkers (a 2000 passat, 2005 ram, and a 2006 elantra). The reader is very simple to use and at $30 shipped (a goldbox special) I couldn't be happier. Saves heading over to Autozone just to have them read and clear whenever the occasional code comes on. Two of the four codes I've pulled were due to loose gas caps...one was a loose knock sensor wire, and unfortunately the ram has a transmission computer failure...3/4 of those would have been silly to go to a shop with, but with this reader they were trips that never happened...
