I just got a Marcum VS500 and I LOVE it!. I like the picture quality much better then the Aqua-VU. The screen is larger (5.5" tube display),nice compact unit w/ built in sun shroud, battery meter, camera direction meter, and it has UV lights, Multi Color lights and the option for no lights all in one. Mine also has the motorized arm which truns the camera. I was not too sure about this option when I ordered it, but it works great. Much better then trying to adjust by hand. I plan on getting some footage for my websites as time rolls on.
