Stiffness is very important. For some folks (like me, in the northeast), it would be nice if the belt doesn't scream "gun."

While I'm pretty sure that there are quite a few good belts out there, and even more not so good, my experience with www.thebeltman.net has been excellent. Stiff, inconspicuous, and good service. I believe that most choices are still a little under $100, or maybe more than a little under $100.
