These saddles are quite popular in Australia at the moment, they're called "halfbreed" saddles, or "swinging fender stocks" and they've been around for a while, although they can differ on how much influence they take from either stock or western saddles. There are lots around however I have never met anyone riding in Clinton Andersons. However, most of these saddles don't have horns.
They're great for many reasons, an example is I don't like riding in traditional stocks, I feel the thigh rolls combined with the deep, curved seat are too restrictive. However many half breeds have slightly "straighter" thigh rolls and the flatter western seat and I like riding in these (and they all have fenders). However some of more traditional rolls, and some have more traditional seats.
They're not cheap here either (saddles are generally more expensive here). You can get more affordable synthetic models, but to go for a good brand leather you're look at at least $2000, and most people go for a custom (usually $3000 up). Being more popular here though, you might be able to find one secondhand and get it shipped over.
Google "halfbreed saddle" and have a look.
