The new Eagle (yes Eagle, wouldn't recommend them before a month ago) 320 DF has all the same features as the Garmin 160 Blue, 500 watts of power, dual freq., speed and temp. as well as the same price ($239), yet the screen is sharper/clearer, similar to the 240 Blue. Garmin hasn't had any competition in this price range till now, soon Humminbird is going to jump in the ring with their Matrix line, probably still won't recommend a Humminbird though.
We have sold more Eagle's lately then Garmin, still waiting on feedback, haven't heard anything good or bad on them, I do know the Garmin's are great units with very few complaints.
