Next Tuesday Apple is hosting its annual iPad-palooza where it will surely show us iPads big and small. But before the big event, you might want to get rid of your old ‘pad to recoup some cash. So where to sell your tablet for the most moolah? To simplify things, we searched for the 16GB iPad 4 with Wi-Fi and the 16GB iPad mini with Wi-Fi. Here’s what we found. eBay: For a while, eBay had an instant sell trade-in program, but it’s done away with that. So if you go with eBay, you’re going to have to do most of the legwork—meaning you name your starting price, and pray to the auction gods that bidders will fight over your used iPad and give you a good price. We’re seeing fourth-gen iPads listed on eBay for $200 to as much as $500. So you have the potential to get a lot of dinero, but there is absolutely no guarantee of how much your gadget will garner.
