The SanDisk Sansa c140 is the 1GB member of the c100 series of music players, and sports all of the advantages of the other c100s in the SanDisk line. The interface is simple and understandable, and it displays album art as well. The c100 series all have FM tuners, support for photos and certain subscription services, and voice recording. More basic than the c200 series, the c100s still offer a good selection of features and overall value.

Although the c100 series was made for the budget-conscious, these models still offer album art and a nice menu system with icons. The screen can handle basic photos, but the screen is small and you have to convert the photo with a special Sansa application before you can see it. This series has good tactile control features and a dedicated button for volume control. Even so, there are some disadvantages to these units, one being a rather chintzy plastic housing and a short battery life. The FM radio recording and voice recordings are also substandard, but in light of the many features the device has, it may not be that big of a problem for the price.

Music organization is one of the better features of the Sansa c100s, and you can browse your selections by song, album, artist, or playlist. Thumbing through the files on a display that only shows three tune names at once can be a pain, though, and it could use an equalizer. However, the tuner and autoscan are well done. Another of the features worth mentioning is the ability to view photographs and listen to music at the same time. If you’re considering this model, though, remember that the battery life is short, and the batteries are not rechargeable. You will only get 15 to 20 hours out of the c100 AAA batteries, so be prepared to replace a lot of them.
