Again, I would like to be allowed to say a few words here even though I am not a warden. I just want to express my opinion. First thing is that the prices listed are way too much in my mind. Second of all, as Quazar mentioned, you do get food, lodging, and armor (and weapons). Also you get the honor of serving those in power and being noticed by them. As I was once a warden, I can say from first-hand experience that you get many other, and more rewarding benefits then minas.
(The purpose of my post was not to insult you for the idea, simply to provide a base for those who agree with me that the Wardens should not be paid.)
