Good brands are Circle Y, Billy cook, Tex tan, Crates, teskeys, Corriente, some people like Dakotas as well,to name a few. If your willing to do the search you can find a good name brand used saddle. Do not my any saddle new for $300, they are loads of crap
Thanks! I have been looking on ebay as they are cheaper there!
Even on E-bay you are unlikely to get a quality, leather saddle that comes from a reputable maker for what you want to pay. Most of the "great deals" you will find on E-bay at that price are going to be poorly made (to the point of risking safety and well-being of you/the horse) and of crap materiel.
