This is not really a Help topic, but more of a suggestion topic.

I am looking for a portable Mp3 player, I currently have 6Gb Ipod Mini, and since I filled it and the battery has been giving me trouble I am thinking about getting something new.

What I want:
20Gb or more
Replaceable battery

If possible
Ogg video support.

I dont want to buy something that will break after a few months so tell me about good/bad experiences you've had in the past.
