Lou,
Sucks for your buddy at DEA, but unfortunately, we holster makers aren't the only ones making sharkskin belts. Most of the good western boot manufacturers who make cowboy boots in exotics also do belts in shark, alligator, stingray, and ostrich.
(Tony Lama, JB Hill, Dan Post, etc.) When I was searching for a source for exotics, JB Hill Co was actually rather helpful. For a look at some quality, non-holster related leatherwork, check out a magazine called "Cowboys and Indians", geared toward southwest art and lifestyle. Some of the ads are truely impressive. Where else can you get a filagree belt buckle hand-crafted in rose-gold for $6,500.00? (Yes, for just the buckle).
