I've sold quite a few iPads and iPhones on Ebay. The best thing to do is start at .99 because the listing fees are lower. Unless you are offering some accessories or something that makes your iPad unique, the listing probably won't get a serious bids until you are within a day of it ending. At that time people start seeing what final selling prices are going for, and the bidding starts. Occasionally you may get a higher price when a couple people get into a bidding war, but if you look at listings ready to end, they are relatively all about the same price. Don't accept bids from those out of the country or from those with very little or no feedback. I won't go into reasons why, but I speak from experience. Avoid Gazelle because they will give you a quote, and then not honor it when they receive your iPad, Also, if they sell for $350 on Ebay, Gazelle will offer you $250, and then they sell it on Ebay.
I have had a could people try to scam me, and had 1 person bid on my iPad and won it, but I saw that he bid on another one which ended shortly after mine, and that iPad had a free case with it. Sure enough, he received mine and said it didn't work and sent it back before even letting me know. I just refunded his money and resold it. I could have proven ti Ebay that he was a scammer, but it wasn't worth the time.
Good luck if you choose Ebay, but most of the time it will work out nicely.
Also, I always pack and ship my unit from the post office, in the presence of a postal employee (go when they are not busy) , while videotaping the sealing of the box. I let the buyer know that when I ship it. That will prevent the guy from saying he got a box containing a book! Plenty of those guys out there.
And this part will probably get me flamed, but the last name of the buyer will sometimes clue you in to whether the buyer will attempt to scam you. It's a shame, but certain ethnicities contain a disproportionate amount of thieves within it. We all know it is true.
