just took delvery today of my standard horizon HX851. Initial impression is very good. I paid about 240 with tax and shipping for it. Comes with the li-ion battery and two charging adapters...one 12V cig for the car and another 120 for the wall. I'm actually kinda amazed at the weight of it...given all the capabilties (floating, submersible, GPS, strobe, etc.) I feel its a lot lighter than I thought with a very good footprint. So far the manual that it comes with seems pretty easy to follow (good for me as I'm a first time VHF owner and don't have a clue what I'm doing) and is very informative.
thanks again to everyone for the input, it was helpful in my purchase.
