aardwolfe - your last point about litigation possibilities is right on. NO manufacturer is going to give people who are already stressed by being in an emergency situation (and hence setting off their PLB) the luxury of choices, because that can come back and haunt them with the possibility of big $$$$$ lawsuits. For example, "Now, Mr. PLB manufacturer, if you had a button for 'Come get me right the heck now!', why didn't you have a button for '*fill in the blank*'? Wouldn't that have been reasonable?" You can see where this is heading - in today's legal climate, more choices equals more legal risk for the manufacturer. Pathetic, but that's the state of affairs, at least in the USA, where people who gorge themselves at McDonald's have actually tried to sue that company for making them fat...
