Its a cdj player that scratches like vinyl and its got 100% (+-) pitch tuning like a real turntable. Great companion for any SP lacking pitch.
Copped one off my friend, brand new in the box for $100.00 but I saw them on Amazon, brand new for $161.00 and at http://www.bandh.com too.
Verdict : Really nice scratching effects and the pitching is really warm without debris. Built is kinda on the plastic-ee side but pretty sturdy. Jog wheel feels good but delicate.
A really good alternative if you are dying for a Pioneer CDJ 800 and a fraction of the price.
