You can get a nice used saddle that is a bigger name for relatively cheap, like others have mentioned.
However, I would like to throw in Corriente
. I know one of the previous posters mentioned them but I actually own and ride in one, as does my brother and several of my friends who are ranch hands. They are a superbly good quality saddle that is made for an inexpensive price. I got mine custom made just the way I wanted it for less than $700, I've been riding in it for several hours a day, every day for over a year now and still love it. It is, by far, the most comfortable saddle I've ever had the privilege of sitting my ass in.
My brother has been using his for feedlot/ranch work for around 8 years and his is still in great shape (and he inflicts more trauma on a saddle in 1 year than most folks could in 1 lifetime). Now don't get me wrong, they aren't the same quality as a saddle from a big name saddler that costs $2500+ brand new, but that doesn't mean that they are poor quality. They are just working quality. They are FQHB with a 7" gullet, which fits most standard stock horses and I will likely never own a different brand unless the size/shape of the horse demands it.
