music for mp4 playersWhat is the best mp4 music player that's out there?

I'm looking for an mp4 music player that plays but videos and music and has an expandable SD card slot. The price is from $0-110. If u could provide a link once u find one that would be great.
MP4s generally break a lot faster than MP3 players. It's best to buy an music for mp4 playersiPod and just convert the MP4s into MP3s using easy to find programs for your computer. If you don't like iPod, another great brand for PC users is Creative. They make beautiful, affordable Zens that play MP3s, might even play MP4s, but if it doesn't, programmusic for mp4 playerss that convert are very simple to find.
The only one that I can think of that fits your criteria is a Sansa sandisk.
I dont think there is one in that price range. There are some generic ipods on ebay that play mp4s' though.
