"Yes, they could save your life if ever used in an emergency but how many of us have $700 to invest in one? I honestly doubt I will buy one in their current design. It would have to half in price, come with better weather resistance and have self service batteries, like CR123s. The concept is excellent, just not very affordable for the masses."

I hear this a lot - yet I see people with nine AR-15s in their collection, or who can afford $600 for a playstation 3 and another $160 for a couple of games...

I'd love for them to be cheaper, don't get me wrong, but for many it's not the cost, it's the priorities. They don't think they'll need one (and most won't).
