I see that Sport Chalet and West Marine both have a $50 rebate coupon on the Spot Connect black interface unit that connects to an Android phone for satellite emergency messaging (etc) service, and the price comes out to basically $100 after the rebate. REI Coop still has the DeLorme Inreach for $250. I understand there is an additional fee for annual signup and service(at least for the Spot Connect and maybe for the Inreach also) and an additional fee for the service plan you select, but what's the best deal between the Spot and the DeLorme systems? It appears that the DeLorme unit comes with a GPS, but I think the Spot has to be connected to an external GPS (not really sure). I hope somebody can suss out the best deal for me (us). Many thanks in advance.
