Selling price for a Dell latitude D620?

[Haas]

I'm selling my 8 month old Dell Latitude D620. Harldy used the first 6 months and been using the last 2 mostly for email and reading news. Evertything works flawless just thinking about upgrading to a Mac. The specs are Intel core duoT5600 @ 1.83GHz988MHz , 0.99 GB of RAMWindows XP What would be a good asking price to sell since it's used but in mint condition? Thanks for your feedback.
