I suppose I know the answer, but I'm going to ask anyway.
I'm using an x50 right now, and while I like it, I tend to miss what I had in my pre-pop 1.8 Valentine (rear antenna, casing, mount, arrows, usual stuff). One of the biggest interests is the newest "J function", which as I understand it, basically points out whether a Ka alert is really police-originated or just from a leaky windshield decoration in a nearby car.
And then there's the RX-65, the successor to my former v980 - I don't care about the voice, so I don't know what reason there is to try this.
It's not like I'd be out $400 since selling the (blue) x50 would recoup the majority of that cost, but ... I dunno. Any significant pros/cons from anyone?
