It's probably a fair price in theory since the species isn't that common and just about any T other than a curly hair or a rosehair is worth $40-$50 at near adult sizes, particularly if female... in theory.
OTOH, I'm with Cooper. I know that a lot of people tend to be "total collectors" and if it's got 8 legs and is a theraphosid they want it, but I think some species just don't need to be in the pet trade and this is one of them.
I would say get it, I have had one of these for about 12 years, raised it from a sling. It was a birthday gift from Bryant Capiz, great spider to have, not very colorful, but not bad looking either. It is kinda skittish but it feeds well. Mine is about 6 inches now.
