well, I have no idea of western saddles, my horse just magically came with one. I would assume a training saddle to be a simpler saddle with no bells and whistles. As I understand it, western saddles come in many different styles and this one looks to me like the inexpensive "trail ride" saddles at the local tack shop. The trainer's iv'e known just had a basic western saddle that they like and that fit them, I don't believe they had a specific style (the one I rode in was good quality but used well) I might also suggest buying one second hand, as it will be more comfortable (in my experience). A high quality used saddle will probably last longer than a cheap new one. Also, don't get too attached, you never know when some horse is going to roll or squash it into a wall.
You want a saddle that's comfortable for you and your horse, so if these saddles are poor quality then you and the horse will be miserable. I hope this helps somewhat, western saddles are mainly used for breaking and then the horse is stuffed into english around here =P
