MP3 Players/MP4 Recorder

I found these in "The Computer", a PC store. There were only three MP3 audio players, two for just under $200. The only brand I can remember is the Rio from Diamond Multimedia. One was advertised for about $50 but the clerk told me it was out of stock (or back ordered?) when I pointed to the ad. They were all PC versions but a Mac version of the Rio is due out soon. I saw an incredible Sharp MP4 recorder, a future video "camcorder" about the size of a cigarette pack, which created QuickTime video files in MPEG4 format.
