I ordered a ScanGuage. Once I get it, I will let you know how it works out for hybriding. If you do a Google for it, you can see it is popular on some of the Ford F-150 forums, etc., where there have been many positive comments and the ScanGuage staff respond to user posts. It looks like some folks got it for an introductory price of around $100 with a $25 dollar (or so) refund a few months ago, though now the selling price is now $129 (including shipping).
