Personally, $1500 is a bit high to me. But that's just me. The site not only has a reputation for going offline regularly, it's been down for a month currently. Gonna be hard to build on that.
I would say $500 tops, and then only if I had a way to make it self sustaining and possibly even turn a little profit.
At the end of the day, anything's "worth" depends on what the buyer is willing to give for it.
