I have had the 996 for almost a year now and would highly recommend it. It does everything that a scanner needs to do plus it has GPS support which I believe the GRE lacks. I never played around with a GRE though. I think Tom has both types so he can probably chime in on this...
Nope, he doesn't (have both the GRE and the 996).
I have been watching the fighting, er discussion, on the 396 group at yahoo about which is "best". Seems general consensous (sp?) is that the GRE is more inclined to overload than the Uniden. That would be important if you were in a dense population area (metro area) which would be the BEST place to use a scanner (to me).
As for the vscanner stuff - not sure that this is a plus (for me). Seems rather odd to me actually. You have to have memory to STORE the information, right? Then why only load 1/21st of it in at a time? In the docs for FreeSCAN I see there is an approach that you can use to "simulate" this with the 996 if you want to go that way. The other thing with the 996 is that you can essentially do this anyway with the startup configuration approach (for one) or the gps coding (for another approach). The example they give in the manual for the startup is a couple places in Texas. The nice thing about the GPS coding is that the radiio will track where you are and switch to the systems coded for that area if you are moving around.
Then there's the NAS (I think is what it's called). At any rate, I believe this is a network number (think it's like a mac address on a network adapater - shows what computer or station is calling). Now why this is so important to the folks that "need" it, I've never heard that part of the explanation. Maybe this is "ignorance is bliss" on my part.
IOW, I'm pretty happy with my 996 and how it performs. Suppose there will always be something else "better" (newer) out there that I can wish for, but not really planning on moving any time soon. If I do something, it would be along the handheld lines because I don't have one that does digital.
More than you EVER wanted to know about how I think, eh? <wide grin>
