I'd be careful of a no-brand, but if it looks alright, some of them can be better saddles than some of the big brand names. My trainer has a no-name roping saddle that is one of the most well made and honestly comfortable saddles I've ever ridden in.
However, I would steer WAAY clear of Buffalo saddlery. I've ridden in a few of their saddles and not only were they uncomfortable for the rider, they are VERY poorly made. Every single one I've seen on a horse has pinched, rubbed or sored the horse even when properly fitted with a properly fitting pad. They also tend to wear out really easily. If you are doing any kind of heavy riding, I would wager it would probably fall apart in less than two years.
Hope that helped. : )
