The "Wilderness 5-Stitch Instructors Belt" is my favorite.

If you intend to carry a firearm, get the "5-stitch" model. It is a webbing belt that is stiff enough to support an inside or outside waistband holster - no problem. The buckle is steel and you can clip a carabiner to it and use it for a "high places" security rig.
