Honestly with the price of PLBs now in the $400-500 range unless you REALLY want the constant tracking feature of the SPOT, in about 3 years you bought a 406/GPS PLB.
You can get a McMurdo Fastfind Max-G for the low $500 if you check around. Another brand I can't remember has an ad in Trade-a-Plane if you are in the market.
With the 121.5 Mhz becoming unreliable for SAR next year, I can't imagine flying around in the backcountry without one of these. The price is cheap when you consider the other crap we spend $$$ on.
Just thought this might help, or further confuse.
Also,,,, It is part of my passenger briefing to show everybody on board how the device works and what pocket of my vest it is in
