Choices

Now that my Zen 16GB is gone I am looking for a new mp3 player. I am thinking of the Zune 80GB but it is a HD. I mow lawns alot (2-3 hors at a time days in a row) on a rider with no suspention (really bumpy). The player would be in my pocket but might this affect the player?

I would really like a radio (voice recorder optional)
I like to have video because I have long car rides with my brother.
Needs to be loud to play over a mower and to play along to with drums (as loud or louder than the Zen)
Good sound quality (I listen to the player 8 hours at a time most days (im going through withdrawls lol)).
No ipods (to many sad stories from friends)!!
No touch screens (in a dark bus it can be blinding)!!
min 20 hour audio 3-4 hour video
Has to fit into a pocket
looks do not matter
price below 250
16GB min
Work on a PC with vista and XP

I like the Sandisk View 16GB but from what I have herd it does not always work and when I tested one it crashed in 30 seconds.

These almost get the requirments
The Cowon iaudio 7 ok but no video
PSP Slim but a 16GB mem card is $200 alone

Any other information is welcome
