Equus 3130 Best Reader for your $

For less than $200 you get a reader with a large backlit screen and one that can also give a live data feed from your car's sensors. It also supports CAN (controller area network) which by 2008 will be a new standard, a standard that Ford and foreign auto makers have already adopted. Did I mention it also comes with a serial cord to connect to your PC? This is a very fun DIY toy you'll enjoy for years.
