I don't know enough to give you much good advice, but I personally wouldn't go for it at that price. According to bikepedia, it didn't go for nearly $900 new. MSRP was $650, and you can often times get bikes for a little less than MSRP. I'd think maybe worth ~$200 if the Dart 2 is an OK fork and if the bike were in good shape, but again, I don't know enough to give much good advice.
