Can anyone help me better understand differences between ScanGauge II (http://tinyurl.com/2zl4no) and Bully Dog's WatchDog Multi-function Performance Gauge (http://tinyurl.com/3vcrt6m)? I've found a fair number of threads/posts about the ScanGauge, but very few about the WatchDog. I recognize the WatchDog appears to have a better display, which comes at a more premium price, but I haven't seen anything that lays-out specific differences and advantages/disadvantages of the two devices.
That said, I assembled the attached table of each device's advertised features/capabilities, to facilitate a side-by-side comparison. Green lines list capabilities that appeared "equal" to me. Yellow shows ScanGauge "advantages". Blue shows WatchDog "advantages".
Is my table complete? (Does either device offer additional capability?)
Is my table accurate? (Are those really differences, or are there more similarities between the two devices?)
Recommendations on which device is better and, more importantly, why?
Is the WatchDog worth the $40-$60 price premium it commands?
