I think you made a good choice, unless SPOT has improved a bunch over the 1st ones. I rushed to the store and bought one of the first SPOT's to hit the market, it was spotty and you never really got a confirmation that your message went through. I really wanted it to work so went out of my way to make sure I got the most from it. I even had troubles standing at the peak of a 7000' mountain on a blue bird day at zero degrees, lot's of mountain peaks actually. I let the subscription expire and the SPOT unit is floating around in a bin full of other electronic gizmo's that have likewise outlived their usefulness.
