The Hercules DJ Control MP3 e2 is ideal for mixing two tracks on two different decks.
This mixer includes a number of easy-to-use, DJ features, such as one-touch synchronisation for tone control, or automatic looping for 1, 2 or 4 beats.
The DJ Control MP3 e2 from Hercules even lets you apply custom effects to audio files, and save your music remixes to other tracks.
What's more, in addition to being extremely compact, the DJ Control MP3 e2 can be used on the move, as it's self-powered through any USB port.
These are used i think, but bargain at that price :D Postage kind of high but still cheap deal.
