I couldn't be happier with my two belts from DM Bullard... I've said this many times, but they are great. Just the right thickness, fine craftsmanship, competitive price, hefty roller buckle. Plus, he has a few standard sizes in stock. I've got a black shark and oil brown and both took around 3 weeks since I like the 7 hole configuration.
I can't comment on how long they'll last since they're relatively new, but they're made from Hermann Oak Leather which from my understanding is some of the finest in the US.
