I'm travelling sometimes and want a cheap mp3 player that can read a really large external memory source, ie a big micro sd / sd card slot (say 200gb or greater) or has a usb socket that can host flash drives (I already have a 256gb one that I could use).  I don't have any interest in high end features and amazing audio quality, just something fairly stable that is usable with a large music database.   If it was really cheap and a bit nasty with a bad interface I'd put up with that, IF it allows a really big external music source to connect to it.The only players I've found that support say 200gb sized micro sd cards are the expensive fiio players which are way more than I want to spend.   I'm not actually sure if any mp3 players can host a usb device, it's just something I'd like to think exists but maybe it doesn't.Anyone know of any players that meet this spec ?   Oh and to clarify, ideally I want something small, ie mp3 player size.
