I have never had any dealings with the Dakota saddles. Corrientes? A lot of dealings with them. I think if you're buying new, they're a best bang for the buck. They also seem to hold their value - a used one locally usually runs only 100-200 or so less than a brand new one. Downside is most people will come up with 100-200 to buy a new one in a specific type and tooling they love, rather than buy a used one. So there's pros and cons there.
I've taken apart a few Corrientes to clean and refurb... I like them. I wasn't sure at first, but over the last couple of years, they've won me over.
One word of caution - their trees are somewhat wide. If you have a big ol' quarter horse, you're golden. If you have something less 'cowboy' like a TWH, or an Arabian, or like me, a mutt that's maybe Spotted Saddle horse and Mustang, their saddles are going to be too wide up front and they don't offer a narrower tree. They DO have several variations on trees (Association trees). I understand they are very helpful on getting you a saddle that fits your horse if you'll call them ask for their recommendations with regard to your horse.
