Overpriced or underpriced is in the eye of the beholder. Just do your homework and see what they have sold for and what add-ons you want your A4000 to have. Shipping cost kind of limits you to where you can buy from. Personnel sales in the 50 - 100 - 150 range really can't be compared to sales through an auction. If I buy one from my neighbor for 50 dollars, this means absolutely nothing to you or the value of an A4000 unless you have a neighbor with one for sale for 50 dollars. This sounds like a nice unit and at least it isn't stripped. One sold on EBay last night where the guy listed the computer seperate from the keyboard and mouse. Good luck!!!
