I'm not a runner (obvious to anyone who's seen me), and I don't know any high-intensity runners. But a quick look at Froogle says that the thing is probably worth at least $75. So ... guess it's time for the rite of passage ... time to enter the world of eBay.
Any tips out there for a first time seller? (In particular, are there things I should do, or not do? Or are there better auction sites out there?)
