Greetings, getting ready to sell my old iPad and was wondering if anyone had an idea of the cost. Costs are all over the board for similar items on ebay. 1st generation iPad. 16gb. wifi only. Great condition. Rarely left it's leather case, never dropped, treated very kindly. Is engraved on the back. Leather(ette?) case does come with it. Any thoughts would be much appreciated! Thanks.
