i would also go with a DJM mixer, because like tommy said, its the industry standard. Also you could save money, when you buy all your stuff from pioneer. i know they do it overhere, recordcase.de for example gives special bundles like www.recordcase.de/lshop,showdetail,1334598738-29626,e,1334598819-10306,,0020106035,,,0.htm
and i bought there my pioneer stuff too, they gave me a good discount! I would check for this, you could save some hundreds!
