02 sensor data loggers, which do you like

The LM-2 can log up to five channels, all it needs is a $12 memory card. I don't remember if it comes with a CD or you download the software to either a desk top or a lap top. Open the program, insert the card, a couple mouse clicks and there are your recordings. It will display real time too. As far as the scanner goes I have no use for it.
