I'm looking to get the best money for my iPad 1 64 GB Wifi, and wondering what you think I should sell it for. I would be throwing in a case and the dock. Is $550 unreasonable? Any places you'd recommend selling it to or should I just go to Craigslist? I'm wary of Amazon because they tend not to have iPads in stock from their side and I would have to go through a seller.
