if you live in a decent sized city I would say use craigslist..... people are more ready to pay more because you dont have to worry about shipping since they can pick it up.
I would say in philly on craigslist for example it would easily sell for $175+ you could even get $225 ish for it if your lucky and the paint is shiny... also be sure to point out the wheels are 700c, because they are usually only found on "nicer" bikes
