I've heard a few guys interested in Brass roller buckles for belts. I've been working hard to try and find a supplier for thiese items and may have found a way to get them. Here is a picture of some sample he sent me and I wanted to get your opinions on them.

He can provide several sizes but only two are represented here, 2-1/4" (top right) and 3" (bottom right). The nickle buckle on the left is 2-1/2".
