There are two versions of the Colorsoft: The base model that came out this summer, and the Signature model that came out last year. Both are on sale right now. Both also did well in our tests (though the Signature is the one that had issues with yellow bars appearing on the bottom of the devices last year) and are mostly similar, but have a few key differences. The Signature Edition has an auto-adjusting warm light, while the basic Colorsoft has a warm light you can manually adjust. You'll get twice as much storage on the Signature, too, with 32 GB over 16 GB, and the Signature can be wirelessly charged.
