Hey guys, I plan to buy a OBD II Scanner soon. I want more than to just get the codes out of the car....I want live data. I'm considering a used Snap-On MT2500, OTC Genisys, AutoXray EZ-Scan 6000, and a PC based Autoenginuity. These scanners vary wildly in price range. I was just wondering if any of you guys had any experience with these units or any others that you might recommend.
