Sorry to hear that. Just write it off to experience and move on, if he's only been ridden that many times he's not really what you want
Not sure if you ever looked at Heritage Farms website but the Rauchers might be able to help you find something - you just have to be very clear about what you want and what you want to pay. Don't go too much off the photos they post as they aren't very good with a camera I think!!
