Thanks to all members for their quick replies to my quandary. I have the i930 on a trial and will hold off buying one until I check out the Foxwell 510 and Launch Creader. Eager to hear news of the Foxwell. One last note: the first thing to do whenever an ABS fault shows up is to clean the offending wheel sensor (if known or all of them - not that much to do) and remove all grease, metal flakes, etc. This rule has solved a half dozen "faults" on three cars, and saved me a proposed $2400 bill on an XJ8 I owned previously - new sensor, cable and ABS module (Ha!).
