That darn DJ equipment can be so back debilitating sometimes. No problem. The Pocket Sized MP3 Player Mixing Deck has you covered for your next gig. It works like a standard mixer and even allows you to preview your next track before mixing. Of course you’ll need two MP3 players for a smooth transition and a headphone jack will let you preview and listen to your work without being interrupted by drunk flusies.
ThinkGeek has it for $25.
