I was not able to find much information on this item but I did find a place that sells them complete for about 1500.00. I am not sure if this is one of the units with a built in wireless adapter or not. I was not ablt to test it because I don;t have the charger for it. It is also missing the stylus. It comes with the unit itself and a rechargeable battery. I am offering a 20 day warranty on this item so that you have enough time to get it charged and make sure it works.
