Pictures* would help a lot, but if you just want to get rid of it I'd say $100 sounds about right. Someone should pay that, I'd think.
*If you post an ad on craigslist without pictures, don't expect many serious responses. I usually skip these ads, as they are usually written by people that:
1. Don't respond to my e-mails.
2. Have no idea what they're talking about.
3. Are too much of a waste of time to deal with. By the time I actually see the bike I almost always immediately see that it's not something I want.
Pictures pictures pictures!
