He's a Nirvana, so asking there might get you more input
I don't know much about Tex, but my Spanish Salty with his hat was about $150 (it was a private sale, so I'm not sure if they go for higher or not). They are much harder to find than Mountain Boys, who show up fairly often but are highly sought after. The Spanish boys don't show up too much, but when they do they're usually on European ebays or here on the Arena.
