Mp3 players

[Killy]

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.

I suggest an IRiver H320 or H340.
H320 = 20gb and H340 = 40gb
Can play videos (dont know what Ogg is though)
Radio
Recognised as external hardrive
Better sound quality than Ipods, a little more expensive.
16 hour battery life from 3 hour charge
Microphone-voice-radio recorder

Its takes a few days to properly get used to the interface and the controls, but otherwise its good.
The only two problems are:

1: Its pretty big, and with the leather case it usually comes with, even bigger.
2: The customer support isnt too good
3: Not sure about replaceable battery.
4: They have actually stopped manufacturing them, even though they were a success. It can still be bought from places though.
