look around, there are many choices! you did'nt say whether you are an auto repair shop or not? If so, i can only speak for myself, after being in the business for 38 years, i have the older genisys obd II system and it still works fine! I have been looking at this new EScan Scan Tool by Automotve test solutions -
www.AutomotiveTestSolutions.com ;also there is
www.pico.com, and I can't afford it, but this is the latest system out! - AXONE3 + TRIBOX mobile from TEXA USA INC. -
