02 sensor data loggers, which do you like
Me too, but I don't log data with it, just for keeping an eye on the ratio.
Cudafever, I think you would be miles ahead getting the Innovate wide band gauge kit with data cables and logging software like we have and then just connect a laptop to it for logging.
$150 or less vs 6-700
Or even possibly this with the logger and scanner so you don't need a laptop.
