Creative ZEN Mozaic - Digital player / radio - flash 2 GB - WMA, MP3, protected WMA (DRM 9), protected WMA (DRM 10) - video playback - display: 1.8" - black
$59.99
I am enjoying this little MP3 player very much. The rewind is fast and uncomplicated. It holds a lot of books, and I like the earbuds. I especially like the fact that it plays almost every type audio book on the market - including protected WMA. Very good price for the quality.

The only Cons are that it occasionally freezes up, but it's easy to reset. Also the buttons are hard to distinguish one from another in the dark. I like to be able to work the controls without having to look at the buttons. I wish a couple of them were at least textured.

Very good little player.

$19.99
This book explains the fundamentals of digital rights management systems including identifying, tracking, authorizing and restricting access to digital media. You will learn how DRM systems help to protect and enforce copyrights, patents, trademarks, and other forms of intellectual property. Digital assets can take various forms including audio, data and digital video. You will discover how it is possible to provide simple access to authorized users (paying customers) and how to restrict access to unauthorized users. Digital media content must be uniquely identified. The common identification codes that may be assigned to digital media include ISBN (books), ISSN (magazines), DOI (multimedia) and watermarks. You will learn that DRM systems may include a DRM controller, digital asset manager and DRM packager that allow DRM systems to receive requests for digital assets, to find and retrieve the assets and to packages (encode) to protect the assets during delivery and use. Digital assets can be monitored and tracked using a variety of information including their distribution addresses (IP address) and through unique identifying characteristics of the digital media such as the use of digital watermarks. Protocols and standards can be used to define rights elements of digital media and services. Some of the DRM languages covered in this book include XrML, SDMI, XCML, ORDL, RDF, REL and others.

DeRosa by Bridgecraft Child/Kid's Drum Set - DRM 312 RED - For 3 to 5 yrs
$89.95
These are really the only way to go when purchasing a very reasonably priced kids' drum set. That being said, you should be aware that the connections between the drums are of poor design and construction. We had the hardest time mounting the drums together, because the drum mounting design simply does not work. I had to get out a screwdriver and pliers to bend the cheap stamped metal enough so things would fit, and they are continually coming undone because they are so shoddy.
