I keep praising the virtues of the 436HP, as my posts on RRDB threads reflect. However, there are some downsides. One of them is portability. As much as I like the 436HP, I find myself using my 396XT when going for long walks and just want to listen to PD, FD, EMS, etc. In fact, I find I'm using my new WS1080 much more for walking and when out and about for the same reason. Frankly, I do have the feeling that a couple of drops and that may be it for the 436HP.
Yes, the P25 decode is a bit better on the 436HP than 396XT and WS1080, this display is nicer, I like the service types, etc. But none of these are enough for me to be carrying it around all day.
So if you're going to be up and around a lot wearing the scanner on your belt all day long, the 436HP may indeed be too bulky and not as well built from a durability standpoint. This is too bad because it was supposed be a handheld scanner with a similar concept to the HomePatrol, but more "handheld friendly."
Like others on this thread, I have had the 396XT for years, dropped it, done this and that, and no problems what-so-ever. Still one of the best scanners out there IMHO.
