I saw one of these before, and before the chorus of iPod suggestions or even Zune suggestions, I have had an iPod before, my only MP3 player ever actually, a 5th gen video for three or four years, and was fairly satisfied with it following liberal application of Rockbox. I was thinking of just getting that same one again, since, as far as I know, Rockbox doesn't exist for the more recent models, except from what I've found getting a new one as such, or even a refurbished one, would cost about the same as getting a shiny new music player all on its own. The reason why I want Rockbox capability and am averse to getting a Touch or Classic or Zune or some such, is that I'd like support for formats beyond MP3. I'm not entirely sure how much this matters as far as experience goes, but as far as convenience goes I have two reasons that I'd like it. The first is that a lot of my music is already is a fairly veritable rainbow of formats (and by rainbow I mean mostly .flac and .mp3 with a few in .wma and .ogg) from collection, and I'd rather not spend an afternoon converting it all. The second is that when I download music, it comes in a variety of formats as well, and listening to it all on my computer seems like it would be a bit restricting. A less practical reason is some nonsensical desire to listen to the music in as close of a form to the artist's intention as possible, even if I have my doubts as to whether I would be able to tell the difference between 320 kbps MP3 and whatever lossless format.
The only other factor that I would consider would be memory capacity; again, for the sake of convenience, I'd like for it to be fairly large. 30 GB at the least, preferably around 60 GB, with no complaints as to more. Video capacity would be nice, but with my previous model, I almost never used it for videos and never for games. Everything else is fairly extraneous; I don't care about size or portability in the least, sturdiness is nice but mostly unnecessary, screen size, whatever. Price is of no concern for the most part, but over five hundred dollars would be a bit of a stretch.
So my question here is whether or not there exists any sort of hipster/audiophile approved brand that I wouldn't know about that fits all of my criterion. Like I said before, I don't mind paying full price for a two or three year old model, but if there's any alternatives I'd like to know about them. Thanks in advance to everyone that takes the time to respond.
tl;dr - I would like a new music player that supports files other than mp3 and has pretty good memory capacity for under five hundred dollars, and would like advice. Thanks in advance.
