Sometimes I see some nice horses in the philly craigslist section of farm and garder. http://www.rainbowridgefarmequestriancenter.com/horses_for_sale.htm
If your want to travel a little further, you should check out Zeus
. I used to board there, probably 3-4 years in total (I used bring my mare closer in the winters.) I was contemplating buying him, but I ended up getting a weanling instead, since I don't have as much time as Id like to train a riding horse, and I don't have a budget to board two horses at a nicer stable with a good ring and still afford all the extra care my mare needs. I havent ridden him, he hasnt been ridden in lessons so I havent watched him being ridden either. He's been at the farm for a while, so they arent in a big hurry to sell, but they don't use him for anything so he's kind of a money pit to them. You could probably strike a deal. He's been there for since atleast early 2008. His trainer, Virginia is really honest, and I love the assistant BM Jon.
The other horse, Odin is VERY overpriced for his age, his training and the market. I know for a fact he's not ridden regularly, because his trainer, the B.M. Never seems to be around.
