02 sensor data loggers, which do you like

i was real close to just buying a gauge with a sensor, and watching it. because that's all i really need.

But it will be nice to take the time to watch a hole 1/4 run, or a 2minute cruise. while i'm not trying to crash my car looking at something besides the road.

I still wonder if this would work. it's not clear if it comes with the Logworks software? But it does come with the computer cable............
