Has some nice ones, but less of them are in your budget, although I was able to find some good ones around there, not sure if they're in your area though. Good website if you looking for sport horses though.
I found Emma on Dreamhorse.com. It's a nice site, well organized and easy to use. Plus you can search by area, price, training, color, size, etc. to find exactly what you are looking for. I put in local area, appy colored, 13 - 14.2 hands and there she was!
