Navplanner 2 is the best $100 you'll ever spend. It has all the HD maps and adding/transferring waypoints is as easy as point and click. It is an awesome product. Just remember that the waypoints are only as good as the maps. The Navionics maps are the best out there, but they still aren't real accurate. They'll get you close, but you'll need to do the rest on the water. Couple this product with Google Earth and you have a real winner. A gpx file from NavPlanner will come directly into Google Earth, so you can see the waypoints you selected in NavPlanner in Google Earth. If the Google Earth imagery is when the lake was low it really helps you visualize what the spot looks like.
