A number of good recs in here already, but I’ll throw in Thirteen50 leather. Got 2 belts from them a couple years ago and they’ve both patina’d beautifully and only gotten better with wear. I think they were about $50 and totally worth it. You pick from like 6-8 different leather colors/types, pick your width, and then pick your buckle style/metal and belt tip shape. Super thick leather and exceptionally good quality for price ratio
