I'm looking for an (affordable) scan tool. A couple I have found are the Auto-Tap (http://www.autotap.com/scantool_selection_guide.html) and the Kal OBD II System Tester-KM9615 (http://www.actron.com/cgi-bin/web_st...=5293273_29504). Any real world experience out there on these OR other reccomendations? Thanks!
