I just checked eBay and couldn't find any that had sold there.

I've had good luck selling stuff, including a bike or two, on Craigslist. Suggest you put it up for sale at your best case price and drop it over time til it sells. Might want to wait a couple months for the peak selling season.

I use the 60% rule in pricing things: If the item is like new, the best price you'll get is around 60% of what a person can buy a new one for.
