...The example below is the exact same specs as a "new" model. I believe it will hold its value quite well. I would sell them for as much as I could get for them and I would expect that number to be fairly high.

Ok so the refurbs are cheaper but surely don't hold their value well in terms of resale? Or would you sell them simply as if you'd bought it new?
