For all you ODB2 folks check this one out. $169 is a heck of a lot cheaper than $2k. - http://www.scangauge.com/

Checks and clears codes, as well as gives you real time info on MPG, engine temps, EGT's, boost, odometer, trip, and tons of other stuff. They are pretty sweet, and pretty compact too. Do I sound like a salesman or what! A co-worker has one and it's pretty sweet.
