I have one made by a company called "Circle T" and it's a lot better quality than most of the ones I've seen. "Hamilton" also makes really nice ones. Someone on another board I frequent has had one on her dog for a few years now, and just going by pictures, it still looks new. There are probably better out there, but both of the companies mentioned above make very nice quality leather. I've had a "Circle T" leash for about 8 years now and it's wonderful, so I don't see how a collar would be any different.
