Keep it on Craigslist. You just need to be patient–I have sold just about everything I have ever tried to sell on Craigslist. Sometimes it takes a day, sometimes a month, but there is always someone out there looking for what you have.
Some tips
–Take some good pictures and post them in the ad
–Be up front about the cosmetic damage
–Be reasonable and willing to negotiate
–Personally, I would not expect much more than $8000 private party sale
