The advantage of 9500ix is its GPS, and the ability to use that to teach it where the false alarms are. IMO that's a minor thing. I've got a V1 and I think its ability to show the direction of the signals, as well as track multiple "targets" at the same time is much more useful. I get very few false alarms, but I've also disabled K and X bands as they're never used by cops in my area.
Oh, and I've bought my V1 and (previous) Escort 8500 second hand for less than half the original price. No problems with either. Food for thought.
