I'm still leaning toward an HDS-5, but have been looking at the HB's as well. Kinda skeered of all of 'em. Lowrances- water/cs issues, HB- gps/cs issues. What's a fella to do? Ifn ya wanna-be (pun intended) helpfull, find someone to buy my barely used motorguide hand control 70#. Also, I really prefer a unit with internal antennae.
