Flash MP3 players - help

I have now an un-opened Lexat Jumpdrive 256MB flash player I got from fry's for 80$. I checked and saw the the prices for the Creative MuVo 256MB, also sum up at arround 75$. Should I return the lexar to get the MuVo? Is it alot better that it would worth going through all of this? Or should I just stick with the lexar? Also, how long is creatives warrenty?

The features I need are 256MB, easy navigation, a litle LCDm light and not really battery consuming (I live in the US)

Thanks, Prexus
