I'm on sites like equine.com and equinenow.com searching for my next horse. Those two sites aren't necessarily the ideal site for me, they look a bit sketchy and since anyone can post, the posters might be sketchy too. I'm looking for a Quarter Horse gelding with a low temperament, preferably bombproof. I need a horse that would not mind working with beginners, but would also be able to compete in dressage and jumping. I need a horse that loves to gallop too, not just trot around. It's gonna be a hard horse to find due to all of my requirements, but the reason for that is i'll be letting beginners use my horse, of course with me by their side. I also will ride it, I'm advanced so I don't want a horse that is slow and only for beginners.

Thanks ya'll
My stables do not have any horses for sale, so sadly that ain't an option. Dreamhorse.com looks good, any other sites?
Oh and I'm in the States, so U.S. only sites please
