I love my brighton belts also, but they simply do not hold up the same way (leather bleeds onto breeches when wet, front and back pieces of leather separate with hard wear). I usually assume my Brighton belts are good for 2-3 years. There is a reason I buy (on ebay) multiples of my favorites.
Elegant, equestrian leather belts, (and much more... ) located in Kentucky. They used to be in Toronto - I remember seeing their leatherworks on display at the Royal Winter Fair, and they were really really beautiful. Simple, classic, timeless - no bling.
For leather care, on their site they recommend Oakwood.

Ok, a little pricey, but my absolute favorite black belt I picked up at Bergdorf's It's gorgeous, the Italian leather will last forever, and I can wear it riding, out, whatever. A friend also picked a gorgeous brown belt up at another department store, I forget from which one, but the point of the story is try to shop outside the tack store and you might find just what you are looking for The worst part about 'cheap belts' is that they are still $50, which is not exactly cheap IMO.
