M_Boats: Handheld VHF radio, and handheld GPS recommendation

I need to replace my VHF radio, and also need to buy a handheld GPS. I'm thinking of a Midland Nautico NT3VP as a radio. I'm also considering a Garmin eTrex Vista HCx GPS. From what I can see on the internet, I can't tell if the GPS unit comes with nautical maps, or if you have to buy them separately. I would appreciate any first hand reports on these two items, or suggestions of something else that would be appropriate for a Montgomery 15. Thanks, Bill Day M-15, 363, "Gee Whiz!"
