I'm looking to get an iPod touch for my 5yo grandson. He has an iPad mini 2, but loves taking pictures and I think he'd have fun with an iPod for that and some games that may play better on a small device. I'm looking to stay on the lower priced end, but don't want to get something that's basically useless. I know I want 32 gb, and I'm looking at close to $200, even used, for a 6th gen. If I have to do that, fine, but if I could go 5th gen, that'd be awesome. Input? We haven't had iPods since we starting using iPhones, so I'm a little out of that loop. Thanks for the help!
