If ebay sold prices are to be believed (which seem insane), that seems like a good "craigslist asking price" starting point.
The market seems to be fairly crazy right now. Service history may be your bargaining leverage.
Depending on what you are after, I would check Barter Town. If you don't really need it, I agree, it's well above my impulse threshold.
Either way, there are much better deals to be had, and 15 WPC would take a bit of planning to make the best of.
