Ottawa Canada Dear Linda, Shaz and List: I expect an Mpower in good working order that has been cleaned in the last year or so would sell for $2,000.00 if it is a 32-cell model, and a bit less if it is an 18. This assumes you have the AC adapter, carrying case and the manual although I believe it can be downloaded from the Humanware web site. If it needs cleaning badly, deduct the cost of cleaning by Humanware from the sale price. Brian
