Open Question: How much should I sell this TV for on Craigslist?

I have a TV that I want to sell. It's listed on Amazon as being for sale for $999.99. It's 1080p LCD HDTV and is 42". I haven't put the advert up yet. Before I do, I want to know how much do you think is a reasonable price. It's in great condition, and was bought just under one year ago. I want to charge $700 (is that fair?), but I've never sold anything on Craigslist before, so I just want to get some opinions on what is a good price.
