In addition to the Sanyo Xacti HD700 there is also the Xacti DMX-HD1000. This is the big brother to the HD700 in that it has a 10X optical zoom. But with this one there seems to be some major limitations that are not making it worth getting. For one thing it has 4MP stills, the HD700 has 7.1MP stills. And the camera that will probably be the best for me the Sanyo E1 Waterproof Video Camera.
For the Wired Kayaker, this would make the most sense. And today the blue version is only $399.00. That is a good price for it. So many choices to make, Sanyo keeps improving their products as well. I am having a tough time choosing.
