Western saddle pads....?

I need some cheap saddle pads for schooling in. I am going to get a nice wool one to go under my show pad, but I would rather have a couple cheaper pads for training in, so I can wash one and still have another to use. I really don't want to spend another $150 on a wool pad, so is there something else that is inexpensive, but comfortable for the horse? I was thinking a fleece one, most of the people @ my barn use them. So yeah, reccomendations?
