The common concensus among people seems to be the Autel brand of diagnostic tools, but even amongst that brand, there is dozens of different options and price ranges. Now, a smart person might say that the more expensive the scan tool, the better it is. But then some of us, aka me, are just a little too dumb and broke to make a decision on that. So, I reckon the question I have is, what's a overall cheap one that can give me a thorough and in depth diagnosis on my rig??
