Erm, i think you can pick them up for about 500 nowerdays, maybe cheaper. Thing is with battle mixers, the build quality is naturally a lot better then standard mixers becuase of the abuse they get. That one is rated as the best on the market, along side the rane ttx range. But you needent have to go for the best to get the benefits of a decent scratch mixer. I have the ecler because im a turntablist, but ive also had a stanton sk2F which was an absolute blinding mixer. The 2 flagship stantons are both around the 300 mark, and i have used this 3 channel one -

Dont just go off my advice tho mate. Try them out, and see what you think. They arnt everybodys cup of tea, but i swear by them. Get yourself down to a decent store and try as many different scratch mixers as posible. Stay away from vestax if you can. The ecler and rane mixers are hard to come by tho becuase they are very specialised mixers...
