I'm in the market for a backpack-suitable one myself.

All I can say is that if you want one to keep in a bag or other piece of kit, don't get the Oregon Scientific models. They're great to keep in the car, boat, at home or office, etc. But the buttons are so sensitive that once you put them in a bag or anywhere they can get jostled, you will hear an endless "beep, beep, beep" and you'll find that your radio is now tuned to the wrong SAME/alert code or is now off the standby/alert mode, etc.

Just something to keep in mind... and issues I wish I had anticipated when I picked it up a few years ago.
