I've been looking into getting a GPS also. If you fish alot of different states and want lake maps for those lakes, Garmin has set up their maps the best. If you fish IL, WI, IA, and MN you can buy the hotspots map for the Central states.(1 MAP @ approx. $100) But the other brands like Lowrance and Magellan, you may have to buy more than one map (2-3 maps @ approx. $100 ea = $200-$300). That really made me stop looking at the other brands. I haven't bought one yet, but I would recommend buying a Garmin based on the fishing maps alone.
