Honda rear disk brake upgrade

[bo]

First off, love my foreman, but drum brakes on the rear???  Ridiculous in this day and age.  I have been looking at a rear disk brake upgrade kit and was hoping to get some feed back before I drop 400 bones.  Just for comparison, a new drum for my machine is over 200.  Anybody installed one? I ride a lot of swamp and deep water so drum brakes don't last long.   Here is a vid with the hero cam on from a couple years ago. http://www.youtube.com/watch?v=KFqcKQ1K1WE
