Hi,

I am interested in purchasing an OBD-II scan tool for my '02 Duramax ZF/6 and am wondering which one is the best price/features. I didn't realize there were quite so many to choose from. We also own a '98 Chevrolet Silverado 5.7 which is OBD-II as well, it would be great if the same unit could be used for both vehicles.

Any advice would be much appreciated.

Thank you,
Tim
