So i'm always having to delete my music from my 16gb nano so i feel its time for something with more memory. I've always had ipods myself, but i heard theres lots of better sounding mp3 players out there that take different formats (FLAC, etc).

I was hoping to get something 80gb+ so my obvious answer is the 80 or 160gb ipod classic, but is there anything else that would be good?
