Best GPS for lakes in AR/MO?


I've got a Garmin 7200 in my truck and love it. I'm thinking about a hand held to use in my bass boat. Although I've never really gotten lost on the lake (at least not for long) I would feel a little better knowing how to get back to camp without searching.
Anyone have a Garmin 76 series and the inland lakes map? That seems to be a good one reading Garmins site. Or any other reccomendations?
