So I'm wanting to go back to iOS after switching to Android. Had the 5 a few months ago and loved it. Found a 16gb 5S on eBay from a seller with good ratings for $340. Comes with the original box and accessories as well as the otter box it's been in since day one. Looks to be in perfect condition. It is out of warranty. My alternative would be to buy a new one for $549 + tax (~$595). What do y'all think I should do?
