I'm hoping to sell my iPad 3 in order to help pay for the Air 2. I listed it on Craigslist and haven't had much response. I've had a couple of offers for $250. That seems low to me. I have it listed at $295 which is a bit less than similar iPad 3s (4G, 32GB) on Craigslist in the DC area. Am I overvaluing my iPad?
