Where can I find a horse for sale in the roswell nm area for cheap or anywhere in general?

I went to a horse auction in Roswell once. They were selling them by the pound for meat. They said they were being shipped to Europe. These horses are very wild, about like Mustangs. I think that selling them for meat has caused the price of horses to go up. After you get a horse you will have expenses like feed, tack, vet bills and so on. Be sure that you can afford all this before you get a horse.
