hello, I'm considering buying a 5s for a relative. Now I'm using a 6 and I'm very pleased with it. So my questions are just the following: 1- is it worth to get it from Apple at $450? Or eBay would be better (for a used phone) 2- in case I decide to buy it on eBay, which would be a reasonable price for a 5s silver (16/32gb) in perfect condition? 3- is it really worth a 2 year phone planning on use it with iOS 9 ? Or a moto x/g would be a better choice ? Thanks guys!
