Her price is fair for her training, I think. And if she was broke correctly, she probably remembers most of the stuff and won't be too hard to tune up either. Her conformation isn't terrible either, though something seems off about those back legs. I'd at least go see her.
She looks nice, and with a bit of work will fill out nicely by the looks of her. If she has a good temperament I can’t see anything particularly wrong with her; if I were you though, I’d be prepared to re-train her from the ground up though, I’d be sceptical of this “green broke” gear, just start over.
