I can't recommend @Equus Leather strongly enough. They are actively involved with the SF community, make a very high quality product and are a joy to deal with. I have a few belts from @Equus Leather and the burgundy is not an exact match to color 8 but still works well IMO. It's their bridle matte brass buckled "West End" at 1 3/8", a width I chose to work well with casual & business casual.
My experience with Equus is great service, great quality, but the leather samples for both belts I ordered were quite different than the finished product (two different types of leather - one suede and one smooth). I always expect some dye lot variation, but these were both significantly different. Considering these are MTO, that's a deal-breaker for me.
