Me either, I have no idea about TW horses but my friend has had one since we were little and he was always such a sweet horse.
I'm crossing my fingers that nothing horrible comes up about her when I go see her, and we are getting her for even less than that actually. 75 square bales of hay on trade. (:
I know absolutely nothing about Walkers either so no confo critique from me but I like her. Sounds like she is what you are looking for too and on trade, can't get much better than that. Hope she's a good fit!
