Top 5 MP3 players with line-in recording

In the world of MP3 players, not unlike the world of fashion, one day you're in; the next, you're out. If you're a passing feature fad, that is. While certain functions have gained and retained traction--playlist support, album art display, photo-viewing capability--many have fallen by the wayside. (Remember the micro hard drive?) One such feature is integrated line-in recording, which allows you to record directly to the MP3 player from another audio source, such as your computer or home stereo set-up. Line-in has enjoyed brief surges in popularity since the inception of the MP3 player, but is currently somewhat difficult to come across. We're attempting to make it a bit easier by rounding up some of our favorite devices that offer the extra. Some of the players below, such as the CC Witness, even have a silence-detection feature that will automatically split tracks as you record.
