Lawrance/Eagle probably have the best repuation in the area. I have seen the 3D Hummingbird models at Cabelas and Bass Pro and they look awsome. Hummingbird has come a long way. My next unit will most likely be the Hummingbird model with side viewing that cost around $3,000. We will see. I currntly run an Eagle 640c with GPS. It has great resolution 640x480 pixals and its dual beam. I am happy with it. Just looking for a few more options.
