Make sure the saddle fits your horse. I don't know what your horse's back looks like but saddles come in different sizes depending on how the horse's back moves and how it sits on it.
Synthetic saddles are nice but what are you planning on doing with your horse? Just trail riding? If you are on a working sort of track with your horse this saddle won't last very long. But other then that, yes 75 is a very good price.
