Just picked up a Pro-162 today since they are still on sale for $179.99 at Radio Shack. I have only used it for a couple of hours today, but so far so good.
I quickly compared the audio from the 162 (Uniden) to the 164 (GRE) in the store. I preferred the 162's audio. Hopefully I made the right choice.
Scan & search speed is fast, text tags are easy to add without the software, programming isn't too complicated.
Compared to my Pro-2054 (basic GRE desktop) and my Icom R-5, I would say the Pro-162 is somewhere in the middle. I understand what some folks say about the GRE models being easily overloaded in RF-heavy areas, having experienced that with my Pro-2054. The Pro-162 seems to have good sensitivity and good selectivity. My area is plagued with repeaters and RF overload.
Edit: After using the 162 today for a few more hours I had the chance to do a little more detailed comparison on VHF-high. I put a (155 MHz) commercial HT antenna on the R-5, 2054, and 162; then used them side by side. I would say now the 162 is closer to the R-5 as far as pulling in the weak signals. (Although none of the radios seem to like computers or internet routers nearby.) I did get a few images here and there while searching through the VHF band. On the VHF airband it seemed plenty sensitive.
Pros: Build quality is very nice, the scanner feels solid and well constructed. Headphone output is limited like most, so you'd probably need an amplified speaker if you wanted to use the 162 while mobile. You can turn the audio up to about 70% before getting any sort of distortion. There is adjustable contrast for the LCD display and the backlight is very nice with just the right brightness, a yellow color like the Uniden BR330T. Instant CTCSS/DCS decoding is right on and very quick. Squelch tail is great.
Cons: The 162 doesn't have adjustable step sizes (no 7.5kHz on VHF for the new channel spacing) and you can't choose the mode of AM/FM. There is no NFM option. Step size for VHF air should be 25 kHz instead of 12.5 kHz. If you're trying to enter a frequency like 154.7275 the unit will round to 154.730. The backlight does not have an option to stay on or come on when any key is pressed. There is no attenuator at all. What would be nice is if Uniden would release a firmware update that addressed these minor items.
