hey you can have mine (500 GB Harddisk) with all the install (mounting plate, Mini dock), fully loaded with 80 GB Mp3 for $150 (plus shipping) if you like. I am based in Europe - Switzerland.
i dont use it so often anymore because i bought a brand new BMW with Navi. device is still great and i wouldnt give it away. but while travelling i also have a 12 inch laptop and no use of the Archos so much.
