The one thing that worries me about the rechargable though is, can it be fed on any kind of batteries besides the rechargable pack? If I am taking it on a camping/hunting trip I wont be able to recharge it. Also, say if the power is out for a few days in an emergency situation like Katrina/Rita or an earthquake how will I recharge it? The nice thing about the M6 is I can stock up on batteries by buying them in most any store, and I dont have to wait for a recharge, I can just keep using it.
