The Duo-DX E-Cassette device is one neat concept – an MP3 recorder which lets you record audio directly from a stereo hi-fi system simply by popping the unit into the system’s cassette deck. No PC needed!

The unit comes with 96MB of memory on board – which can be expanded to 160MB using MMC (i.e. SD) cards – uses Ni-MH rechargeable batteries and is priced at $199.99 from Radio Shack.
