Not exactly the same, but for me, much more useful. I bought a Scan Gauge II.
It does a ton of stuff. It'll read codes including the data from the ECU from the time the code was set (I think they call it the FRZ data). It's got a nice trip computer that will tell you lots of info, max speed, max water temp, max rpm, etc...., for the tank, the trip, the day, and yesterday. It also allows you to display up to 4 different gauges from ECU data simultaneously. And it'll let you reset codes and tell you when the ECU is ready to be checked (you can't reset a code and then immediately get your car inspected).
Yes, it's more expensive ($170 on their website), but it does a ton of other stuff. I really like mine.
I have mine always in my car mounted at the bottom of my dash.
