I think $600 is high esp. for a local sale. That price could work if you live in a large city with an active craigslist. That bike would not easily command that price where I live (a middling sized city in the Midwest) even though Treks move fairly easily. If that's the case, then Ebay may be your best bet (but that's a pain). It would sell quickly on this site as well (but you'll have to join). It won't command top dollar but you should get a good price if you do that.
