I blew 180 bucks on a used Snap-on multimeter once and still haven't figured out half the buttons, so I'm probably the last guy to give advice on scan tools. But honestly with your mix of Asian cars the Autel was the move, those Snap-on units are great for domestic stuff but they can get weird with Hyundai and Kia stuff. I ran into the same software headache when I got my Autel, had to call their support three times just to get the thing to download the right firmware pack.
